The correct choice for the infinitive phrase in the sentence is C) to go to the concert tonight, as it includes the infinitive 'to go'. An infinitive phrase consists of 'to' plus a verb, which makes option C the only correct answer. The other options do not represent an infinitive phrase by themselves or are part of a larger grammar structure.
