Xerophytes exhibit a number of special features in their morphological organs. Usually leaves of xerophytes are reduced or modified to various kinds of structures to minimise transpiration. The following types of condition are seen: (i) Microphyllous when the leaves are small scaly (Casuarina, Asparagus) or needle like (Pinus) (ii) Trichophyllus when the leaves are covered with hairs (Nerium, Calotropis (iii) Macrophyllous when the leaves are soft and fleshy (Begonia) (iv) sclerophyllous when the leaves are stiff and hard. (Banksia). Many xerophytes have no leaves (Capparis) or they fall very early (caducous) as in Euphorbia.Therefore, the correct answer is option C.
