Answer 1

The correct option is A Joint

Leaves are of two types, simple leaves and compound leaves. Compound leaves are further divided into pinnately compound leaves and palmately compound leaves. In palmately compound leaves, the leaflets arise from a single point at the tip of petiole. It is further classified into unifoliate, bifoliate, trifoliate, quadrifoliate and multifoliate depending upon the number of leaflets. A unifoliate compound leaf can be differentiated from simple leaf in having joint or a winged petiole.

Thus, the correct answer is 'Joint.'
