Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?f=179&p=88386#p88386)

The correct answer choice is (B).

If K is the fourth valve opened, then N, P, and G must be the first three valves opened, not necessarily in that order (if K is fourth, then there are three spaces before K, and N, P, and G are the only three valves that can be opened before K). Accordingly, answer choice (B) could be true and is correct.

Answer choice (A) cannot occur because there is no room for I among the first four valves.

Answer choices (C) and (E) cannot occur because G and P are among the first three valves opened.

Answer choice (D) cannot occur because O must be opened sixth or seventh.
