Answer 2

Step-by-step explanation:

A. Adding a square in the top left corner increases the perimeter.  It removes one side and adds three.  So the perimeter increases from 14 to 16.

B. Adding a square in the top center leaves the perimeter the same.  It removes two sides but also adds two sides.  So the perimeter is left at 14.

C. Adding a square to the bottom center decreases the perimeter.  It removes three sides and adds one.  So the perimeter decreases from 14 to 12.
