Answer 2

Answer:

D) They are opposite and parallel.

Step-by-step explanation:

Given:

There are two vectors "a" and "b" have opposite directions having the same magnitude of 7.

If the two vectors "a" and "b" have opposite directions mean one moves right and other moves left.

Which means they are opposite.

Here they have a same magnitude of 7. So they are parallel.

Therefore, the answer is D) They are opposite and parallel.
