Which starts vs that will be starting

[Arnold99]

I’d rather watch the US Open tennis .......................................................
a. competition, who starts from 9.30pm;
b. competition which starts from 9.30pm;
c. competition, that is starting from 9.30pm;
d. competition that will be starting from 9.30pm.

I went with (d), but this one is a bit confusing for me - I think (b) works as well. I'd like to know which one is correct and why. Thanks.

Generally, things start at a certain time; they are shown from a certain time.

None of the above is correct.

Where did you find that exercise?
