Maximum development of face takes place in:

 # Maximum development of face takes place in:

A. 1st to 3rd  week of intrauterine life

B. 3rd to 8th week of intrauterine life

C. 9th to 12th week of intrauterine life

D. After 12th  week of intrauterine life

The correct answer is B. 3rd to 8th week of intrauterine life.

The maximum development of the face takes place during the 3rd to 8th week of intrauterine life. This is the critical period for the formation of the facial structures and features such as the eyes, nose, mouth, and ears. During this time, the embryonic tissue undergoes complex interactions and transformations that ultimately give rise to the characteristic appearance of the human face. After the 8th week, further growth and refinement of the facial structures continue, but the basic blueprint has already been established.
