Answer:
Option A.
Step-by-step explanation:
The vector shown in the figure has components on the x axis and on the y axis.
If each small box on the draw represents a unit, it can be seen that the vector has a component of<u> length equal to 1 on the positive y-axis </u>and a length equal to 4 on the positive x-axis.
Look at the attached image
The sum of these two components results in the vector shown in the figure. Therefore the correct option is option A.
The length is equal to 1
