D
Correct answer
Explanation
The word 'obstetrician' comes from Latin 'obstetrix' meaning midwife - one who assists in childbirth. While modern obstetricians are medical doctors specializing in childbirth, the term originally referred to midwives who helped deliver babies. The other options incorrectly interpret the etymology or assign modern medical specializations.
C
Correct answer
Explanation
Fingerprints begin forming around the 3rd month of fetal development and are fully complete by the 6th month. The unique patterns are created by fetal movement and pressure in the womb. This timing makes fingerprints an excellent identification marker that remains unchanged throughout life.
