lisabon 2012 [21]

Answer: the answer is B which is stationary

Explanation:

This type of front behaves like a warm front only that it is quiescent because the front barely shifts its position. The weather may also be similar to that of a warm front. The two abutting air masses run almost parallel to the front because none is stronger than the other to cause displacement.
