In this question 

We apply BODMAS rule,

$$\begin{gathered} \begin{array}{l}\text{So, (8792}-\text{4136) + ? = 145.5}\\ \\ \begin{array}{l}\Rightarrow \text{\hspace{0.17em}\hspace{0.17em}(4656)}÷\text{? = 145.5}\\ \end{array}\end{array} \\ \Rightarrow \text{ ? = }\frac{\text{4656}}{145.5}\text{ = 32} \end{gathered}$$

Hence, Option B is correct.
