The somatic chromosome number of pecan nut is:

Correct option is A

The somatic (diploid) chromosome number of pecan (Carya illinoinensis)—commonly referred to as the pecan nut—is 2n = 32.

• This means its haploid number (n) is 16, reflecting usual diploidy in its somatic cells

So, the correct answer is:

The somatic chromosome number of pecan nut is 2n = 32.
