4)JS

Option B is correct that is .

It has magnitude, direction, and follows the law of vector addition.

As the direction is given from J to S. our JS vector becomes .

Thus, option B is correct that is .

More about the vector link is given below.

The correct option is;

Step-by-step explanation:

The given diagram consists of a a starting point, J having a direction passing through the point S and the line has one arrowhead on the right pointing to infinity, which is the symbol for a ray, JS

The denotation of a ray is made by the name of the ray having an overhead arrow as follows;
