imo D by all means!

from stimulus only 1 area has S=R; ratings (1-10)
Option D) says in 3 areas, R=10 whereas in those areas S <= 8 (at best)
This leaves the last area where S=R. Now regardless of what you assume in the last area, R emerges ahead of S.

C says Steve's lowest score was less than or equal to Robert's highest score. Also as per the passage we know that same evaluation is in only one of four areas.

Let's say Steve's lowest is 5 and Robert's highest is 5.

You know Steve can not go below 5 and Robert can not go beyond 5.

So robert's avg = (a+b+c+5)/4
Steve's avg = (x+y+z+5)/4

we know each x, y and z is greater than a, b and c. This clearly shows that Steve's avg is greater than Robert's.

HTH!!!!

Two naval cadets-Steve and Robert-received the same the evaluation in only one of four areas.

Your comment doesn't make much sense, how is C safer than D?

I agreed that C is also a right answer, thus there must be two "correct" answers to this question. My question was how you come up with the thought process that C is somehow "safer" than D.

I think this question is messed up. Author might have forgotten about 'same evaluation is in only one of four areas' condition. Anyways, I don't think it is really very worth question to waste our time. If this is GMAT Prep or OG question, then we must understand the logic. But I think this is not that quality of question
