The displacement vector 11ea7ff9_2a6b_9857_a768_4d226ae1e42a_TB2295_11 is perpendicular to the velocity vector 11ea7ff9_2a6b_9858_a768_f9c04a9132d9_TB2295_11 at the highest point of the trajectory. This means that the acceleration vector 11ea7ff9_2a6c_0d8d_a768_bfd6ba145591_TB2295_11 is perpendicular to both the displacement and velocity vectors. Therefore, option D is true.
