Given the two concurrent vectors, let's determine the vector which represents the direction of the concurrent vectors.
Here, we have the vectors:
The vector which shows the direction will be the resultant of the two concurrent vectors.
Hence, we have:
The direction which best represents this will be diagonal of the parallelogram which forms the two vectors.
This can be called the adjacent side/leg.
Therefore, the correct vector is vector C.
ANSWER: C
