Answer:

Option 4: Bassima evaluated (-2)² as -4

Explanation:

The complete question is as shown in the attached figure.

By reviewing the steps of the evaluated expression:

The first Line: 2(12-14)²-(-5)+12 ⇒ True

The second line: 2(-2)²-(-5)+12 ⇒ True

The third line : 2(-4)-(-5)+12 ⇒ Wrong

We can note that Bassima evaluated (-2)² as -4 and this wrong

(-2)² = -2 * -2 = 4

The answer is the last option: Bassima evaluated (-2)² as -4
