Answer:

B. -1

Step-by-step explanation:

it is plainly visible.

the dot is one unit to the left (x- or Real-axis), which is -1.

and it is 3 units down (y- or Imaginary-axis), which is -3.

the number is therefore -3i - 1

the question was only for the real part (without any "impact" by an "i"), which again is -1.
