A
18
B
9
C
27
D
36
Explanation: 

Detailed explanation-1: -The basic chromosome number of carrots is 9–11. Most cultivated carrots are diploid (2n = 2x = 18).

Detailed explanation-2: -Therefore the answer option ‘gametes will have 9 chromosomes’ is correct.

Detailed explanation-3: -Through the process of fertilization, egg and sperm join to make a cell with 46 chromosomes (23 pairs), called a zygote. For each chromosome pair, one homologous chromosome came from each parent. They have the same genes arranged in the same order, but there are small variations in the DNA letters of those genes.
