I think it would be the option "C"

Renewable energy is generally defined as energy that is collected from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services.
A non-renewable resource (also called a finite resource) is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. An example is carbon-based, organically-derived fuel. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas.
The answer is size. The larger
the DNA molecule the slower it travels through the gel. This is because
of the restriction of their movement through the pores of the gel. The smaller DNA molecules travel furthest. The size
of the pores can be varied through by changing the mixture ratios of the agarose gel.
This individual is a healthy carrier.
A healthy carrier (sometimes called asymptomatic carrier) refers to a person whose organism is infected by a microorganism (virus, bacteria, parasite) without presenting any clinical manifestation.
This absence of reaction may result either from a weakness of the infectious agent or from the effectiveness of the defenses of the subject.
Nevertheless, a healthy carrier can transmit a disease to other people. This is for example the case of hemophilia or certain genetic pathologies.
