Options
- AA-III, B-I, C-IV, D-II
- BA-IV, B-III, C-II, D-I
- CA-III, B-IV, C-I, D-II
- DA-I, B-IV, C-III, D-II
Correct answer
C. A-III, B-IV, C-I, D-II
Step-by-step solution
The ovule is a small structure attached to the placenta by means of a stalk called the funicle (A-III). Each ovule has one or two protective envelopes called integuments (B-IV). Opposite the micropylar end is the chalaza, representing the basal part of the ovule (C-I). Enclosed within the integuments is a mass of cells called the nucellus, which contains abundant reserve food materials (D-II). Therefore, the correct matching is A-III, B-IV, C-I, D-II. Answer: A-III, B-IV, C-I, D-II
