Question

$\text{A, B, C}$ are three numbers. 
Let $@ \text{(A, B)} =$ average of $\text{A}$ and $\text{B}$,  
$/ \text{(A, B)} = $ product of $\text{A}$ and $\text{B}$, and 
$\text{X(A, B)} = $ the result of dividing $\text{A}$ by $\text{B}$ 

Average of $\text{A, B}$ and $\text{C}$ is given by

• A. $@(/(@(/\text{(B, A)}, 2), \text{C)}, 3)$
• B. $\text{X(}@(/(@\text{(B, A)}, 3), \text{C)}, 2)$
• C. $/(@(\text{X(}@\text{(B, A)}, 2), \text{C)}, 3)$
• D. $/(\text{X(}@(/(@\text{(B, A)}, 2), \text{C)}, 3), 2)$
