NO because of Conflict Phobia
You are afraid of angry feelings or conflicts with people. You may believe that people with good relationships should not engage in verbal “fights” or intense arguments. In addition, you may believe that disclosing your thoughts and feelings to those you care about would result in their rejection of you. This is sometimes referred to as the “ostrich phenomenon” — burying your head in the sand instead of addressing relationship problems.

The prepositional phrase in this sentence is c. "to your sentence structure", because it is postmodifying an infinitive phrase (to bring complexity), which has the same value, in this case, as a noun phrase. Besides it is composed by a preposition (to) and a noun phrase (your sentence structure).
Option a. is a verb phrase as well as option b. In the same way, letter d. is not a prepositional phrase as it is an adjective phrase used in the comparative form.
