The options you have given all are wrong. The answer will be 2 square root (10).
If we substract from the first end with the last end then we get the vector to be 6i-2j.
The magnitude of it is square root (6^2+(-2)^2)= square root (40)= 2 square root(10)
I hope my answer helps you. All the very best for your future endeavors!
