Answer:
C. 1
Step-by-step explanation:
We can see that each box in the grid is one unit.
We count one box to the right on the horizontal axis and 4 boxes down on the vertical axes to obtain the components of vector v.
See graph in attachment.
Therefore the components of vector v is
[tex]\binom{1}{-4}[/tex].
The length of the x component is 1 unit
Hence the correct answer is C.
