The correct option is C Compound leaf
When a leaf is composed of small leaf like structures called as leaflets, it is called as a compound leaf. The blade of a compound leaf is divided into several leaflets. Each leaf, whether simple or compound, has a bud at its base on the twig. There are no buds at the base of each leaflet. We can expect a bud at the base of each petiole, but no bud at the base of each leaflet of the compound leaf. That is how we can distinguish a leaf from a leaflet.
Thus, the correct answer is option C.
