Options

A. P could be Opuntia whereas Q could be pea.
B. R could be Hibiscus whereas S could be pumpkin.
C. P could be rose whereas R could be mango.
D. Q could be grapevine whereas S could be pea.

Answer

D

Explanation

Plant P has a photosynthesising stem, so it can be O puntia. P cannot be rose plant, as it does not photosynthesise through its stem. Plant Q has a stem that supports for climbing. so Q can be grapevine. Q cannot be pea as pea plant has leaf tendrils for climbing around the support. Plant R has leaf that helps in reducing water loss from the plant. Both Hibiscus and mango do not have this modification. Plant S has leaves that support for climbing hence S could be pea. S cannot be pumpkin as it does not have any leaf modification for climbing.
