Best answer

Here the most frequently used person is $R$ - so we should fill $R$ first. That's points $2$ and $3.$ We get

$T \_\; \_ R \_ U\_\;\_$ (Assume there is a circular connection between either ends)

After this only one opposite position will be left (positions $3$ and $7)$ -- which is needed for $(S, W)$ as per given condition $1.$

So, straight away $C$ is the answer.

Counter examples for options A, B, and D can be as follows:
