Answer 3

With the infinitive "to study" leading its following phrase, "to study difficult equations" is the infinitive phrase.
It is being used as an adjective, because it is helping to describe the noun "equations," using the word "difficult."
It isn't being used as a predicate nominative because it isn't naming a noun.
It isn't using a noun as a subject, because "morning" is the subject, not "equations."
It's not modifying a verb or adjective, so it isn't being used as an adverb either.
The correct answer is A! :)
