Soy la hija de Maria.
Soy "la madre de mi hija," y la hija de Maria es "la madre de mi hija," asi soy la hija de Maria.
(The original sentence says:
"If Maria's daughter is the mother of my daughter, what am I of Maria?"
The mother of my daughter is the same as saying yourself - you are "the mother of your own daughter" - and the sentence says that "the mother of my daughter" (you) is the daughter of Maria, so you are the daughter of Maria.)
