Which statement about fetal growth is correct?

• A. Fetus grows at a variable rate depending on maternal activity
• B. Between conception and birth the fetus grows at a consistent rate within the uterus
• C. Growth stops after the first trimester
• D. Fetal development is fastest after birth

Answer: (B)

Fetal growth is an ongoing process that occurs inside the uterus from conception through birth, driven mainly by placental support and fetal genetics rather than the mother's activity. Growth continues throughout pregnancy, does not halt after the first trimester, and most development and maturation happen before birth. That makes the idea that the fetus grows at a steady in-utero pace from conception to birth the best fit among the statements.
