He competed with the Hapsburgs for dominance:?

1) He competed with the Hapsburgs for dominance:

2) He was the only leader who united warring factions separated over the issue of religion. Of the same choices who was it?

A. Philip II

B. Louis XIV

C. Frederick I

D. Peter the Great

Which one is it? I put B. Louis XIV on both of them and I was wrong.

1) Philip II was a Hapsburg (kind of), and I REALLY don't think that it was Peter the Great.So was it really Frederick I? That doesn't make sense to me.

2) I don't really understand, could it really be Frederick I as well?

Explain please! Thanks!
