The value of -7 ÷ [5 + 1 ÷ 2 - 4 + (4 of 2 ÷ 4) + (4 ÷ 4 of 2)] is:

Answer: Option D

$$\begin{array}{rl}& -7÷\left[5+1÷2-\left\{4+\left(4\text{ of }2÷4\right)+\left(4÷4\text{ of }2\right)\right\}\right]\\ & =-7÷\left[5+\frac{1}{2}-\left\{4+2+\frac{1}{2}\right\}\right]\\ & =-7÷\left[5\frac{1}{2}-6\frac{1}{2}\right]\\ & =-7÷\left(-1\right)\\ & =7\end{array}$$
