20,000–25,000 genes.
Explanation: the human genome contains roughly 20,000–25,000 protein‑coding genes. The other choices refer to different things: the four names are DNA bases (A, T, G, C); humans have 23 pairs of chromosomes (not pairs of genes); and ~3 billion is the number of base pairs in the haploid human genome.
