A must be parallel to b.
Proof:
∠3 = <span>∠13 (given)
</span>∠15 = <span>∠13 (vertically opposite angles are equal)
Since </span>∠13 = ∠3 and ∠13 = ∠15, ∠15 = <span>∠3
Then, a must be parallel to b (transverse line d cuts parallel lines producing converse alternate angles that are equal (ie </span>∠15 = <span>∠3))
</span>

7 / 12 = 0.583333333
Divide them all to see which one equals 0.583333333.
A.
8 / 13 = 0.615384615
B.
10 / 15 = 0.666666667
C.
14 / 19 = 0.736842105
D.
21 / 36 = 0.583333333
Therefore, your answer is D.
