Three is the right answer.

I think the answer is 2. Definition of equal vectors is that both vectors should have the same magnitude and same direction.
For example, two vectors F and -F have the same magnitude but are in opposite direction. So they are unequal vectors. Hence the answer is 2 (option A).

The Correct answer is "2". It is even approved by our physics lecturer.
Let's take an exampl: -5 and 5.
(-5 is not equal to 5, so there are 2 unequal forces)
-5+5=0.
Hence proved.
