Answer» Correct Answer - A A plant with the `C_(4)` pathway is advantageous over a plant with a `C_(3)` pathway as the former can occur in low `CO_(2)` concentrations. When the weather is hot and arid, the leaves close their stomata to reduce water loss. This closure results in low `CO_(2)` concentrations and thus, leading to both loss of RuBP and inhibition of Calvin-Benson cycle. |
