2.48

3.12

4.24

The correct answer is Option 2. 48

Step-by-step explanation:

The given equation is 3x² - - - (1)

When we substitute the value of x we get the value of the equation.

Here it is given that,

x = 4

Substitute this value in the equation (1) we get,

3x² = 3 * (4) ² = 3*16 = 48

Therefore the correct answer is Option 2. 48
