A
False
B
True
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Simple leaves are single leaves that can not subdivide into leaflets. These leaves attach to a twig with the help of the petiole or stem. Compound leaves can divide to mid-vein and form multiple leaflets or blades on a common rachis. Also, sometimes the leaflets can be compound.

Detailed explanation-2: -A simple leaf is a leaf blade that is one piece, although it may be deeply lobed, divided or dissected. A compound leaf is a leaf with 2 or more distinct leaflets.

Detailed explanation-3: -Three major venation patterns in simple leaves are “palmate”, “pinnate”, or “parallel” (Figure 17, left to right). Typically there is a prominent central vein (the midrib) running from the leaf base to its tip.
