Explanation

Cattle (Bos taurus) typically have 60 chromosomes in females and 62 in males. However, standard veterinary and biological references often cite the diploid number as 60 for cattle generally, but more precisely, cows have 60 and bulls have 62. Given the options, 60 is widely accepted as the general diploid count in many textbooks, but 62 is also technically correct for males. Wait, let me double-check. Actually, the standard diploid number for cattle (Bos taurus) is 60. Bulls have 60 chromosomes too? No, bulls have XY sex chromosomes. The total count is usually cited as 60. Let's verify. Cattle karyotype: 2n=60. Yes, 60 is the standard answer. So B is correct.
