Explanation: 

Detailed explanation-1: -Under high temperature, high light, and the current CO2 concentration in the atmosphere, the C4 pathway is more efficient than C3 photosynthesis because it increases the CO2 concentration around the major CO2 fixating enzyme Rubisco.

Detailed explanation-2: -Rice, wheat, oats, cotton, tobacco, sugar beets, and spinach are some examples of C3 pathways. Maize, sugarcane, and sorghum are some examples of C4 pathways.

Detailed explanation-3: -C3 plants include around 95% of the shrubs, trees, and plants. While C4 plants are defined as the plants that use the C4 pathway during the dark reaction. The chloroplasts of these plants are dimorphic and unlike C3 plants the leaves of C4 plants possess kranz anatomy. C4 plants include around 5% of plants on earth.
