A plant in your garden avoids photorespiratory losses, has improved water use efficiency, shows high rates of photosynthesis at high temperatures and has improved efficiency of nitrogen utilization. In which of the following physiological groups would you assign this plant?

The correct option is B C4
Of the given options both C4 and CAM plants have modifications to avoid photorespiratory losses and use water efficiently.CAM plants absorb and store carbon dioxide through open pores in their leaves at night, when water is less likely to evaporate. During the day, the pores, also called stomata, stay closed while the plant uses sunlight to convert carbon dioxide into energy, minimizing water loss. But they often have low photosynthetic capacity, slow growth, and low competitive abilities as their photosynthetic rates are limited by vacuolar storage capacity.
However of the two, C4 plants have a higher rate of photosynthesis in direct sunlight.
Hence the plant in your garden avoids photorespiratory losses, has improved water use efficiency, shows high rates of photosynthesis at high temperatures and has improved efficiency of nitrogen utilization, is a C4 plant.
