Solution

The correct option is B If both the assertion and reason are true but the reason is not a correct explanation of the assertion
A leaf having a single or undivided lamina is called simple leaf. The lamina can have different types of incisions, which may reach upto half (-fid), more than
half (-partite) or near the base or midrib (-sect). Depending upon the pinnate or palmate venation, the incisions are known as pinnatifid palmatifid, pinnatipartite, palmatipartite, pinnatisect and palmatisect.
