Detailed Solution

Assertion (A) is correct. Flowers in Pisum sativum are zygomorphic.
Reason (R) is also correct. Petals are with three different sizes in Pisum flowers. While there are five petals in total, they are not all identical in size or shape. Instead, the pea flower has three types of petals, i.e., the standard (the largest petals), wings (flank the sides of the standard petals) and keel (fused together to form a boat-like structure beneath the standard and wing petals).

Both (A) and (R) are true and (R) is the correct explanation of (A).
