Option:
A. S scores the highest.
B. R is renked second.
C. T is ranked third.
D. Q is ranked fourth.
E. U scores the least.
Answer: A . S scores the highest.

Justification:

In terms of scores, we have :
V > P, P > Q  i.e. V > P > Q.
If R scores the highest, we have R > ...... > T,
If S scores the highest, we have S > ...... > Q or S > ...... > U.

If V ranks fift, P and Q coming before it will occupy sixth and seventh places respectively i.e. Q ranks least. So, S will score the highest.
