In this question 

We follow BODMAS rule,

$$\begin{gathered} \begin{array}{l}\Rightarrow \text{1485}\times \text{? = 594}\\ \\ \begin{array}{l}\text{So, 1485}\times ?=594\\ \end{array}\end{array} \\ ?\text{\hspace{0.17em}= }\frac{\text{594}}{\text{1485}} \\ \Rightarrow \frac{2}{5} \end{gathered}$$

Hence, Option A is correct.
