Step 1: Instead of listing the whole row again, check each statement by elimination using the key sub-blocks already known: the O-T-P-R block (seats 8, 9, 10, 11) and the V-N-U neighbourhood (seats 4, 5, 6), with S at seat 7.
Step 2: The claim of three people between P and S fails because only seats 8 and 9 (O and T) lie between P (seat 10) and S (seat 7), which is just two people.
Step 3: The claim that W is between M and V fails because M and V are themselves adjacent (seats 3 and 4), leaving no room for anyone between them, and W sits at seat 2, outside that pair.
Step 4: The claim about S and O being neighbours to the immediate right of T fails because the seat immediately right of T (seat 9) is seat 10, which holds P, not S or O.
Step 5: That leaves the claim about N. From the V-N-U block at seats 4, 5, 6, N sits exactly at seat 5, directly between V (seat 4) and U (seat 6). This statement holds.
\[\boxed{\text{True statement: N is sitting between V and U}}\]
