it strengthens his ability to persuade through emotions.
it strengthens his ability to persuade through credibility.
it decreases his ability to persuade using logical ideas.
it decreases his ability to persuade using his reputation.

Explanation:

A passionate tone in a speech is an emotional appeal. Emotional appeals (pathos) are a way to persuade an audience. Credibility (ethos) would come from his reputation or credentials, not tone. A passionate tone doesn't decrease logical (logos) or reputational (ethos) persuasion. It directly ties to emotional persuasion.

Answer:

A. It strengthens his ability to persuade through emotions.
