Questions & Answers about Marie choisit un vernis simple pour ses ongles, mais elle ne met presque jamais de parfum au travail.
Choisit is the 3rd-person singular present tense of choisir. The subject is Marie, so French uses elle choisit.
By contrast, choisi is usually the past participle, as in Marie a choisi.
The sentence is in the present indicative. In this kind of context, French often uses the present to describe habits, usual behavior, or general facts, not just what is happening right now.
So the sentence suggests this is the kind of choice Marie typically makes, and that she almost never wears perfume at work.
