Explanation: Transitive verbs need a direct object to complete their meaning. The direct object of the verb "llevar" is "el ###########", this is a masculine and singular noun, so the direct object pronoun is "lo" that matches gender and number with the object it replaces. The indirect object is "su hija", which is a singular noun and the indirect object pronoun is "le" because it has to match in number with the object it replaces. When the direct object and indirect object pronouns appear in the same sentence, the indirect object pronoun is always written first and replaced with "se", so in this sentence it is "se lo".
########### = word not allowed.
