If $$S = C - \frac{B}{4} = C - \frac{8}{4} = C - 2$$, then maximum score can be $$40$$ ($$42$$ correct answers) and minimum score can be $$-2$$ ($$0$$ correct answers). So, $$-2<=S<=40$$, hence $$I$$ and $$II$$.

IMO D)

Since the student attempted 42 questions and left 8 unanswered, then equation becomes
S=C-$$\frac{8}{4}$$==> S=C-2

so now out of remaining 32 questions he can do only 4 correct in that case his score would be 2
if he gets all 42 correct den score is 40
but to get score 41 he needs to get 43 correct which is not possible

so D

but score of 40, 41 are not possible as even if he answers all 32 correct , max score he can get is 30 hence A

The number of correct answers can be 42. Please read the previous explanation.

Maximum score which can be scored is when all 42 are correct

So max score=42-8/4
=40

So any score below and equal to 40 can be answer

Below 40 is applicable as we don't know how many are correct.Number of correct will change score

So from options only 2 and 40 are answers
