Solution

The correct option is D
7

Marks awarded for one correct answer = +5
Marks awarded for one incorrect answer = -2
Marks awarded for unattempted answer = 0
Out of the 7 questions Ram attempted, 3 are correct while 4 are incorrect.
So, the total score = 3 $\times$ (+5) + 4 $\times$ (-2)
= 15 - 8 = 7
Therefore, Ram's score is 7.
