Correct option is D
Because Q sits next to R and
not next to T, Q and T cannot be immediate neighbors.
Typical arrangement might be: R–Q–S–T (in a circle).
S is to the left of T means if T faces center, S is on T’s left side.
In such arrangement, Q is actually to the
right of R (not left) if we move clockwise R -> Q -> S -> T.
Hence “Q is to the left of R” is incorrect.
