Answer
(b) B+C+F
Work Step by Step
The correct answer is: (b) B+C+F
Let's move vector C so the tail of vector C is on the tip of vector B. Let's move vector F so the tail of vector F is on the tip of vector C (in vector C's new position). If we start at the origin, the path B+C+F reaches the point that is one unit directly below the origin. Therefore, B + C + F is not equal to zero.
The three other vector sums are equal to zero because the sum of the vectors would end at the origin.
