What is this asking?

¿Cómo eres?

choices would be:
This question asks about
about a person's health
about what a person is like
how a person is feeling today
what a person is wearing

I think it is about a person's health or how a person is feeling today?

Thank you

No, that would be ¿Cómo estás?

The question asks about what a person is like

Thank you

The question "¿Cómo eres?" is actually asking about what a person is like. It is asking for a description or characteristics of the person. It is not specifically asking about a person's health, what they are wearing, or how they are feeling today. So the correct choice would be "about what a person is like."
