B. Me llamo Ernesto <span><em>¿Cómo te llamas? </em>means "What is your name?" </span> A.<em> se llama Ernesto </em>translates to " it is called Ernesto" and wouldn't make sense when referring back to the context of the question.
<em />C. <em>te llamas Ernesto</em> translates to "your name is Ernesto" and it has the same problem as A
D. <em>soy de Ernesto </em>translates to "I am from Ernesto" and also doesn't make sense
So that means B. <em>me llamo Ernesto</em>, which means "my name is Ernesto," is the correct answer.
