Answer:
The correct answer is B: To fix things, Henry spoke to him about the problem, but he didn't listen.
Explanation:
An infinitive phrase represents a construction that consists of the infinitive form of a verb and it also contains different complements (e.g. direct object) and modifiers (e.g. adverbs). It can act as a noun, adjective or adverb.
In the examples A, C and D there is no construction that contains an infinitive form of the verb, as these sentences are in personal verb tenses (past continuous, past simple and present simple).
Option B contains a construction that contains the infinitive form of a verb - To fix things and it acts as an adverb, so this would be the correct answer.
