I believe the answer is B.
To be parallel the lines must have the same gradient (which in this question is 2). The answer must either be B or D.
To find the correct one you can substitute in the value of X and see which gives the value of Y we are looking for.
Equation B:
y=2x+5
=2×3+5
=6+5
=11
Equation D:
y=2x-19
=2×3-19
=6-19
=-13
We are looking for a value of 11 so B is correct.
