Explanation

Why (d) is correct

In C₄ plants, the Calvin cycle takes place in the bundle sheath cells, which have RuBisCO.

Why the other options are wrong

(a) · your answer Mesophyll cells lack RuBisCO, so the Calvin cycle cannot run there.
(b) · your answer Mesophyll cells only carry out the first fixation by PEPcase.
(c) · your answer Epidermal cells do not carry out the Calvin cycle.

NCERT point: C₄: fixation in mesophyll, Calvin cycle in bundle sheath.
