Answer:
The answer is 'te presento'.
Explanation:
In Spanish 'Te presento a' is used to introduce someone. We normally add the person's name or their relationship to us or both, for example:
- Te presento a mi novia.
- Te presento a Lucía.
- Te presento a mi hermana Pepa.
The other phrase 'mucho gusto' is an equivalent of 'nice/glad to meet you'. And ¿cómo está? is an equivalent of 'how are you?'.
