» Explain it
A
4 × 1 = 4,

4 × 2 = 8,

8 × 3 = 24,

24 × 4 = 96,

96 × 5 = 480,

480 × 6 = 2880,

2880 × 7 = 20160

D
By applying the 'Hit and trial' approach we get to understand that the required value of '?' is equal to the sum of the respective numeric values of positions of the given letters in English alphabet.

W + O + R + D + S + S

= 23 + 15 + 18 + 4 + 19 + 19 = 98

Option D is hence the correct answer.
