A) A-3, B-1, C-2, D-4
B) A-4, B-3, C-2, D-1
C) A-3, B-2, C-1, D-4
D) A-4, B-2, C-3, D-1
Correct Answer: B
Solution :
Orthrotropous ovule In this case, the micropyle, funicle and chalaza lie in a straight line. Anatropous ovule It is completely inverted. The funicle and the micropyle lie side by side. Amphitropous ovule It is curved ovule with horse-shoe shaped embryo sac. Circinotropous ovule This ovule turns over completely, forms complete circle around the ovules and the micropyle faces upwards.
