The correct response to show agreement would be:
"A mí también."
This means "Me too" in English, indicating that you also like skating.
The other sentences either express disagreement or are incomplete:
- "No me gusta cantar" means "I don't like to sing."
- "No gusta esquiar" is missing the subject and should be "No me gusta esquiar," meaning "I don't like to ski."
- "A mí tampoco" means "Me neither," which would be used if the other person had expressed a dislike for skating.
