I guess the answer is B !! as it has no relevance and is not an observation !!

Answer:
Compounds from different organisms are being used widely bu humans for their benefits. Some of the compounds are used as drugs. For example, penicillin is used as a drug or antibiotic. There are many plants which provides humans with other types of medicines and herbal remedies. There are other compounds which are used for cancer treatment. For example, taxol is a compound obtained from trees which are being used as anticancer drugs.
Solar- technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.
Hydro- a hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity
Tidal- energy is a form of hydropower that works by harnessing the kinetic energy created from the rise and fall of ocean tides and currents, also called tidal flows, and turns into unusable electricity
Wind- turns the propeller like blades of a turbine around a rotor, which spins a generator, which creates electricity
OTEC- plants pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity
Biomass- is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity
Geothermal- power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth’s surface. The steam rotates a turbine that activates a generator, which produces electricity
Recently, we found that across several C 4 grasses, leaf width (LW) correlated positively with g sw and negatively with iWUE. Here, using 48 field-grown genotypes of Sorghum bicolor, a C4 crop suited to dry and hot environments, we validated these correlations. Three times a day, we monitored leaf gas exchange and modeled leaf energy balance together with structural characteristics as possible iWUE predictors.
The underlying causes of variance in intrinsic water-use efficiency (iWUE = net photosynthesis/stomatal conductance for water vapors, gsw), particularly in C4 plants, are not well understood. Recently, we found that across many C4 grasses, leaf width (LW) associated negatively with iWUE and favorably with gsw. Here, using 48 field-grown genotypes of Sorghum bicolor, a C4 crop suited to hot and dry environments, we validated these correlations. Three times a day, we monitored leaf gas exchange and modeled leaf energy balance together with structural characteristics as possible iWUE predictors. LW associated favorably with gsw, interveinal distance of longitudinal veins, and the proportion of stomatal aperture relative to maximum while negatively with iWUE, stomatal density, and interveinal distance. Modeling of the energy balance revealed that broader leaves especially during noon when air temperatures approached 40°C, required to open their stomata more to produce a higher negative leaf-to-air temperature differential. These findings demonstrate the crucial part LW, which affects stomatal aperture and coordinates vein and stomatal characteristics, plays in forming iWUE. LW might therefore be used to forecast sorghum genotypes with greater iWUE.
