To solve for A, we need to isolate A on one side of the equation. We can do this by first subtracting 1 from both sides:

3A + 1 - 1 = 16 - 1

Simplifying:

3A = 15

Now we can isolate A by dividing both sides by 3:

3A/3 = 15/3

Simplifying:

A = 5

Therefore, the best choice is to first subtract 1 from both sides (C), then divide by 3.
