At birth, is the least developed of the senses.
a. smell
b. hearing
c. touch
d. vision

Smell and hearing is the most strongest senses a baby has after it's birth. It hearing though develops over the past week. But his/her eyesight develops over the next year. Which would mean the answer is option D "vision" since how it takes a baby over year for their vision to develop fully.

Hope this helps!
