Sure, let's simplify the expression step by step:

Given expression:
[tex]\[ 4(20 + 12) \div (4 - 3) \][/tex]

1. Evaluate the value inside the parentheses:
[tex]\[ 4 - 3 = 1 \][/tex]

2. Evaluate the addition inside the other set of parentheses:
[tex]\[ 20 + 12 = 32 \][/tex]

3. Next, perform the multiplication:
[tex]\[ 4 \times 32 = 128 \][/tex]

4. Finally, perform the division:
[tex]\[ 128 \div 1 = 128 \][/tex]

Therefore, after simplifying the expression, the result is:
[tex]\[ 128 \][/tex]

So, the correct answer is:
[tex]\[ 128 \][/tex]
