Let's solve the expression \(2(4-1)^2\) step by step:

1. Start with the expression inside the parentheses:
[tex]\[ 4 - 1 \][/tex]

2. Subtract 1 from 4:
[tex]\[ 4 - 1 = 3 \][/tex]

3. Now, take the result (3) and raise it to the power of 2:
[tex]\[ 3^2 \][/tex]

4. Calculate \(3^2\):
[tex]\[ 3^2 = 9 \][/tex]

5. Finally, multiply this result by 2:
[tex]\[ 2 \times 9 \][/tex]

6. Perform the multiplication:
[tex]\[ 2 \times 9 = 18 \][/tex]

Therefore, the value of \(2(4-1)^2\) is 18.

The correct answer is:
C. 18
