Discussion

Explanation:

Coding:
R got 6 in one parameter, this can only be Coding. [In none of the other parameters, R can get 6 since he is ranked 3rd or 4th in other parameters]

Total score in Coding = 4 × 3 = 12
∴ P, Q and S score a total of (12 – 6 =) 6 in Coding.
Also, in Coding, R > P > S > Q
∴ R = 6, P = 3, S = 2 and Q = 1

​​​​​​​

Technical Skills:
Total score in Technical Skills = 4 × 5 = 20.
Q > S > R > P
Sum of 20 is possible in two ways (7, 6, 5, 2) or (7, 6, 4, 3)
P scores the least in Technical skills, hence, he get a score of 3 since he already scored 3 in Coding.
∴ Score of (Q, R, S, P) is (7, 6, 5, 2)

​​​​​​​

Networking:
Total score in networking = 4 × 4 = 16
P > Q > R > S
P is first in networking but he did not score 6 in networking, hence he would have scored either 7, 5 or 4 in networking.
If P scores 4, others will have to score 16 – 4 = 12 which is not possible (max sum possible is 1 + 2 + 3 = 6).
If P scores 5, others will have to score 16 – 5 = 11 which is not possible (max sum possible is 2 + 3 + 4 = 9).
If P scores 7, others will have to score 16 – 7 = 9 which is possible when (Q, S, R) is (5, 3, 1) or (4, 3, 2)
Since S scored 2 in coding he cannot score 2 in Networking, hence
(P, Q, S, R) = (7, 5, 3, 1)

Temperament:
Total score in Temperament = 4 × 5 = 20.
S > Q > P > R
Sum of 20 is possible in two ways (7, 6, 5, 2) or (7, 6, 4, 3)
Since R scores 3 in Networking, he cannot score 3 in Temperament.
∴ Score of (S, Q, P, R) is (7, 6, 5, 2)

We get the final score table:

​​​​​​​

R did not score 7 on 7 in any of the parameters.

Hence, option (a).
