Answer:
CR
Explanation:
Thinking process:
This is a question of vectors.
There are a few things to remember about vectors:
A point AB is denoted by the notation AB, starting from the point of origin to the end point.
In the answers, CR satisfies the question
AC is the opposite, so it is rejected as the direction is not the same as the arrow.
Similarly, RC is rejected
AR is the point somewhere on the line not the origin.
This leaves us with CR as the correct answer.
