A.to train,jumping B.training,for jumping
C.to train,jump D.to train,to jump

D.

Do you think it's hard to train a horse to jump.

Here "train" means "teach"

You can't use "jumping" here...

But like this:

The horse is good at jumping.
Look at the horse jumping over the ditch.

You can say:

Do you think it's hard to training a horse to jump.

This is also ok.
