MULTIPLE CHOICE QUESTION

Is the relativistic rule V = (v1 + v2) /(1 + v1v2/c^2) consistent with the fact that light can have only one speed in all uniformly moving reference frames? How?
Yes. If either v1 or v2 is equal to c, then V = c.
Yes, but only if both v1 and v2 are equal to c does this reduce to V = c.
No. If v1 or v2 is equal to c, then this does not reduce to V = c.
No. If both v1 and v2 are equal to c, then this does not reduce to V = c.
