I understand the usage of opt to (do something) and opt out (of something), but I'm a little confused about opt vs opt for. For example:
Which Subjects did you _____?
I _____ philosophy; he, however, was thinking of ______ criminology.
What is the correct usage in the above sentences, opt or opt for?

To my ears, "opt" always needs a preposition after it.
Looking for exceptions, I hit on this article, which purports to list the prepositions which can follow "opt", in order of frequency. The most common is "for" followed by "out", "into", "to", and "in".
Of course the one you choose (or "opt for") depends on your specific circumstance.
In your examples (where the thing to be selected is a simple noun), "opt for" is appropriate.
In the second sentence, using that expression twice sounds a little clumsy though. One of those opt fors could be replaced by a form of "to choose", which means exactly the same thing. Something like:
But "opt" without any preposition (as in: "Which subjects did you opt?") is not idiomatic.
