Which of the following is an innate ability in an infant?
a. learning to play with a pet
b. playing with blocks
c. recognizing a parent
d. smiling

Good morning!
 
Of the above skills only the letter d (which refers to the ability to smile) is correct. Children learn and socially construct all other alternatives. It would be impossible for a child to be born knowing who their country is for genetic reasons alone. Playing is also an acquired practice in society.
 
hugs!
