Given below is a diagram showing four different types of placentation labeled A, B, C, and D. Match the figures in List I with their corresponding examples in List II. List I List II A 1 Dianthus B 2 Pea C 3 Argemone D 4 Lemon Choose the correct answer from the options given below:

Step-by-step solution

Figure A shows marginal placentation, where the placenta forms a ridge along the ventral suture of the ovary and ovules are borne on this ridge forming two rows. This is characteristic of Pea. Thus, A matches with 2. Figure B shows axile placentation, where the placenta is axial and ovules are attached to it in a multilocular ovary. This is seen in Lemon. Thus, B matches with 4. Figure C shows parietal placentation, where ovules develop on the inner wall of the ovary or on the peripheral part. This is found in Arge
