By the end of which month is the gender of a fetus usually determined?

Explanation:
Understanding when gender can be seen in ultrasound is the key. External genitalia start to differentiate in the middle of pregnancy, and by about 14 to 16 weeks they’re usually distinct enough to identify the fetus’s sex. That timing corresponds to the end of the fourth month, which is why this option is the best choice. After this point, gender identification tends to be even more reliable, though it can still depend on fetal position, amniotic fluid, and the quality of the ultrasound image. Earlier than about 14 weeks is often too early for clear visualization, so it’s less dependable.
