The phrase that best answers the question "¿cómo eres?" (How are you?) is "soy alto y guapo" (I am tall and handsome).
In the question "¿cómo eres?" (How are you?), the speaker is asking about your physical appearance or characteristics. The options given are descriptions that could be used to answer this question. Let's break down each option:
"Eres baja y bonita." (You are short and pretty.) - This describes someone as being short and attractive, but it might not be the appropriate choice if you're describing yourself and you are not short.
"Estoy divertido." (I am fun.) - This phrase does not directly describe physical characteristics. Instead, it suggests a personality trait of being enjoyable or entertaining.
