Answer:

B. Sometimes  

Step-by-step explanation:

Opposite angles of a parallelogram are always congruent, and consecutive angles are always supplementary (first image).

However, consecutive angles can be congruent if they are each 90°. The parallelogram is then a rectangle or a square (second image).

Thus, pairs of consecutive angles of a parallelogram are sometimes congruent.
