If you want to create a parallel structure, you need to use the same form of the word throughout the sentence. So here, there are two adjectives, tall and quiet, meaning that the third word also has to be an adjective. Very mysterious, somewhat handsome, and well dressed are all adjectives, but will wear all black is not, which is why that is the correct answer.
Plus "to". Example: He wants to run outside. "To run" is the infinitive phrase.
Prepare what you are going to say! If you just say something without thinking first, it can escalate the situation even more. Hope this was helpful ;)
