Three vectors A, B, and C add together to yield zero: A + B + C O. The vectors A and C point in opposite directions (anti-parallel) and their magnitudes are related by the expression: A = 2C. Which one of the following conclusions is correct? C) B and C have equal magnitudes and point in the same direction C) A and B have equal magnitudes and point in opposite directions C) B and C have equal magnitudes and point in opposite directions C) A and B point in the same direction, but A has twice the magnitude of B C) B and C point in opposite directions, and B has three times the magnitude of C
