Question

clear all
diploid; haploid
haploid; diploid
triploid; diploid
diploid; triploid

Explanation:

To solve this, we analyze the concepts of ploidy (haploid, diploid, triploid) in biology. Typically, gametes (sex cells) are haploid (n), and somatic (body) cells are diploid (2n) in most organisms. If the question relates to the ploidy of gametes and somatic cells (a common biology topic), the correct pairing is haploid (gametes) and diploid (somatic cells), so the option "haploid; diploid" is correct.

In biological ploidy, gametes (e.g., sperm, egg) are haploid (have one set of chromosomes), while somatic (body) cells are diploid (have two sets). The option "haploid; diploid" matches this typical ploidy distribution.

Answer:

B. haploid; diploid (assuming the second option is labeled B, as per the visible options where the second radio button is "haploid; diploid")
