Answer:
B
Step-by-step explanation:
Vectors are drawn as lines with arrowheads on them.
Vectors can be added together by drawing the arrows nose to tail.
To add vectors A and B, place the tail of vector B at the nose of vector A (see attached diagram).
The single vector that goes from the start to the end of the combined vectors is called the resultant vector.
As R = A + B, then R is the resultant vector of A and B.
R starts at the tail of vector A and goes to the nose of vector B.
