Solution
The correct option is C Assertion is correct but Reason is incorrect
In xerophytic leaves, spongy parenchyma is reduced. Palisade parenchyma may occur on both upper and lower sides with spongy parenchyma sand witched between the two, e. g., Nerium. In Nerium or Oleander, the lower surface bears deep depressions called crypts (stomatal crypts). The crypts possess a number of scrutinize hair and stomata. In other xerophytic plants,stomata occur individually and are sunken below the surface due to their being overtopped by accessory or subsidiary cells.So the correction is 'C'.
