Equation, rephrased:An object thrown directly upward is at a height of h feet after t seconds, where h = -16 (t - 3)^2 +150. At what height, in feet, is the object 2 seconds after it reaches its maximum height?
A. 6

This is a great example of how GMAT questions often exploit our experience with similar questions. In the real world, a question of this nature would concern the MAXIMUM height that the object reaches. In fact, most students have probably solved tons of questions in which they were required to find the maximum height of some object. The GMAT uses this experience against us and asks for the height 2 seconds after the maximum height is reached.
