• B.
• C.
• D.

Answer: (D)

Verified step by step guidance

1. To find the vector A - B, we need to understand that subtracting a vector is equivalent to adding its negative. Therefore, A - B is the same as A + (-B).
2. The vector -B is the vector B with the same magnitude but in the opposite direction. In the image, vector B is pointing downward, so -B will point upward with the same length.
3. To perform the vector addition A + (-B), place the tail of -B at the head of vector A.
4. Draw the resultant vector from the tail of A to the head of -B. This resultant vector represents A - B.
5. Examine the options provided and choose the vector that matches the direction and relative length of the resultant vector A - B.
