Answer:
C. parallel phrases.
Explanation:
Parallelism means that the same form of a word is used throughout a particular sentence; for example, only gerunds are used, or only participles, etc. In this case, infinitive phrases are used: <em>to levy war, (to) conclude peace, (to) contract alliances, (to) establish commerce, to do all other... </em>All of these phrases are infinitive, and thus, parallel.
There aren't any clauses in this sentence (it's a simple sentence) and therefore B is incorrect. A doesn't exist in grammar as a term.
