I would say B). Hope this helps!
Answer:
a. synergism
Explanation:
When two different drugs inhibit a single biochemical pathway of microbes less quantity of each drug is required in combination to produce the effect than when used separately. This effect is called synergistic interaction of drugs.
Both beta-lactam antibiotics such as penicillin and cephalosporin and clavulanic acid serve as beta-lactamase inhibitors and inhibit the beta-lactamase-producing bacteria. Therefore, beta-lactam antibiotics and clavulanic acid are used in combination to control these enteric bacteria.
It should be 3! That is the only logical answer to the question...
Carbon capture and sequestration
While it's not a power generation technology, carbon capture and sequestration—technologies that allow for the scrubbing of carbon from power plants for storage in underground reservoirs—may finally be coming of age after years of trial and error.
Technology pilot demonstrations at coal-based power plants in places like Australia and the U.S. have sparked new interest in the technology.
The hope is, it could become an enabler for other technologies, such as biomass or algae-based biofuels that produce carbon emissions. That's because organic fuels pull carbon from the atmosphere before converting it to fuel.
