A.
23
B.
63
Answer
C.
68
D.
14

Answer: Option B

Solution

Answer: Option B
Solution:
The number of chromosomes in the wheat endosperm is 63.
The endosperm is a tissue produced inside the seeds of most the flowering plants following double fertilization. It is triploid (meaning three chromosome sets per nucleus) in most species. Wheat has 21 pairs of chromosomes, as the endosperm is triploid.
Thus, it will be 21 × 3 = 63.
