The gestation period for cows is approximately 9 months, or more specifically around 280 days. This duration is similar to the human gestation period and is crucial for the development of the fetus. During this time, the embryo undergoes significant growth and development, ultimately resulting in a healthy calf at birth.

Other options provide incorrect durations, which do not align with the typical reproductive cycle of cows. The first option suggests a very short gestation period that is not biologically feasible for livestock. The third option of 61 days is significantly less than the necessary time for a cow to carry and develop a fetus. Lastly, the fourth option of 16 days is far too brief for any mammal gestation, demonstrating a misunderstanding of reproductive biology in larger farm animals like cattle. Understanding proper gestation times is essential for effective breeding management and ensuring the health of both the mother and her offspring.
