Match List \(I\) with List \(II\)
List \(I\) List \(II\)
(A). Rose (I). Twisted aestivation
(B). Pea (II). Perigynous flower
(C). Cotton (III). Drupe
(D). Mango (IV). Marginal placentation
Choose the correct answer from the options given below :

A \(A-I, B-II, C-III, D-IV\)
B \(A-IV, B-III, C-II, D-I\)
C \(A-II, B-III, C-IV, D-I\)
D \(A-II, B-IV, C-I, D-III\)

Verified Solution

Answer & Solution

Correct Answer

(D) \(A-II, B-IV, C-I, D-III\)

Step-by-step Solution

Detailed explanation

Rose have half-inferior ovary, thus it is known as Perigynous flower.
In Pea, the placenta form a ridge along the ventral suture of the ovary and ovules are borne on this ridge forming two rows.
In Cotton, twisted aestivation is present.
In Mango, fruit is drupe.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
