We have to draw the sitting arrangement for the given conditions. First of all, there are six people P, Q, R, S, T, and U who are sitting around a circular table and facing one another. It means that they facing toward the circular table. Now, "P" and "Q" are sitting in front of each other.

It means "Q" is sitting in the middle of "T" and "R".

So, the final arrangement will be: [ alt="F3 Madhuri Engineering 12.04.2022 D19" src="//storage.googleapis.com/tb-img/production/22/04/F3%20Madhuri_Engineering_12.04.2022_D19.png" style="width: 197px; height: 224px;"> As it can be seen that "T" is sitting opposite "S". Hence, the correct answer should be "T".
