As per the given information,
R sits 3rd to the right of T. R does not sit at an extreme end of the row.

Only three persons sit between P and U. P and T are not adjacent to each other. So, we will eliminate Case II and continue with Case I.
I sits opposite to U.

K sits 4th to the left of I.
J sits opposite to the person who sits immediately right of S.

More than two persons sit between K and M.
N sits 2nd to the left of M.
Thus, Q and L sit in the vacant positions of the rows.

Hence, this is the final arrangement
As per the above arrangement, the first and second persons in each pair given in options are opposite to each other except for the pair K-R.
