Answer: B. (4, -2)

Explanation:

The vector shown in the image is (2, -1)

Now, the scalar multiplication for vectors works in the next way:

for a scalar c and a vector (x,y)

c*(x,y) = (c*x, c*y)

In our case, the scalar is 2, and the vector is (2, -1)

2*(2, - 1) = (2*2, -1*2) = (4, -2)

Then the correct option is the option B.
