The position of floral organs in relation to the ovary can be categorized as follows:
Step 1: In Figure (a), the floral organs are attached at the same level as the ovary, so it is Perigynous.
Step 2: In Figure (b), the floral organs are also attached at the same level as the ovary, so it is Perigynous.
Thus, the correct answer is (4) (a) Perigynous; (b) Perigynous.
