Answer:
Correct Answer: B
Solution:
A leaf having a single or undivided lamina is called simple leaf.
The lamina can have different types of incisions, which may reach up to 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.
