Solution

The correct option is A gets larger.
A metal sheet with a circular hole is heated. The hole gets larger.
When the metal sheet expands, it doesn't expand radially from the hole, it expands circumferentially as well i.e. circumference of ring expands in the same ratio as the width of the plate. So, hole gets larger.
