• D. solved

Answer 1

Answer: (C)

to solve

The infinitive verb is a verb with the word 'to' in front of it. This verb is always just a verb. There is no - ed, no - ing, no - s at the end of the verb. Thus, options A, B and D are wrong according to the rule. The correct option is C since 'to' is in front of the verb 'solve'.
