A Correct answer
Explanation

Most humans have 12 pairs of ribs (24 total), but anatomical variations exist. Approximately 1 in 200 to 1 in 500 people are born with an extra rib (cervical rib), which is a slightly higher frequency than the '1 in 20' claimed, but the statement correctly identifies that extra ribs do occur in a small percentage of the population.
