Answer: D

Explanation:

Let's carefully analyze the problem:

The student wrote:

x = +2;

This does not increase x by 2; it just assigns the value +2 to x.

To increase x by 2, the correct statements are:

x += 2; → This is shorthand for x = x + 2;. ✅
x = x + 2; → Explicitly increases x by 2. ✅
x = 2; → This assigns 2 to x, it does not increase it. ❌

So the correct options are A and C.

Answer: (d) Both A and C
