In this question 

we apply BODMAS rule,

$\begin{array}{l}\text{\hspace{0.17em}4003}\times \text{77}-\text{21015 =?}\times \text{116}\\ \\ \Rightarrow \text{ 308231- 21015=?}\times \text{116}\\ \\ \Rightarrow \text{\hspace{0.17em}287216 = ?}\times \text{116}\\ \\ \Rightarrow \text{\hspace{0.17em}? = }\frac{\text{287216}}{116}\text{ = 2476}\end{array}$

Hence, Option D is correct.
