Formal:
* Me llamo [Your name]. (My name is [Your name].)
* Mi nombre es [Your name]. (My name is [Your name].)
Informal:
* Me llamo [Your name]. (My name is [Your name].)
* Soy [Your name]. (I am [Your name].)
* [Your name]. (This is a more casual way to answer, just saying your name.)
Remember:
* "Me llamo" is the most common and polite way to answer.
* "Soy" is more informal and is often used with friends and family.
* "Mi nombre es" is also formal and is used in situations where you want to sound very polite or professional.
