Well lets try and do it with all of your choices
a.9 times 15=135
6 times 20 =120
135+120=255
A.255


b.10 times 15=150
4 times 20=80
150+80=230
B.250



c.13 times 15=195
4 times 20=80
195+80=275
C.275


d.15 times 15=225
5 times 20=100
225+100=325
D.325








So the closest to 300 would be C
