The answer is B. subtract 11 from both sides.

When solving an equation, we want to isolate the variable on one side by performing the inverse operation of the operation being performed on the variable.

In the given equation, the variable "a" is being added to 11. To isolate "a," we need to perform the inverse operation, which is subtracting 11. By subtracting 11 from both sides of the equation, we maintain the equality of the equation.
