15. This is how you ask someone their name in Spanish:
a. ¿Cómo te llama usted?
b. ¿Cómo te llamas usted?
c. ¿Cómo te llamas tú?
d. ¿Cómo se llamas usted?



Answer :

In Spanish, the correct way to ask someone their name is:

c. ¿Cómo te llamas tú?

Here's why:

1. "¿Cómo te llamas tú?" is the informal way to ask someone their name in Spanish when speaking to someone around your age or someone you're familiar with. It translates to "What is your name?" in English.

2. Option a. "¿Cómo te llama usted?" uses the incorrect conjugation of the verb "llamar" (to call) with the formal pronoun "usted." The verb should be "llamas" to match the pronoun "usted."

3. Option b. "¿Cómo te llamas usted?" is almost correct, but in Spanish, the informal pronoun "tú" is usually used instead of "usted" when speaking in informal situations.

4. Option d. "¿Cómo se llamas usted?" also has a conjugation issue. The correct form of the verb "llamar" with the pronoun "usted" is "llama," not "llamas."

Remember, when asking someone's name informally in Spanish, you should use "¿Cómo te llamas tú?" to be grammatically correct and culturally appropriate.
