Final answer:
The appropriate indirect object pronoun is 'le'. Example: Quiero la sal. Le pasas, por favor?
Step-by-step explanation:
The appropriate indirect object pronoun to fill in the blank in the sentence 'Quiero la sal. la __ pasas, por favor?' is le (Option A).
Example: Quiero la sal. Lela pasas, por favor? (I want the salt. Can you pass it to him/her, please?)
The pronoun le is used when the indirect object is in the third person (him/her/you formal). In this case, 'la' is the indirect object referring to a person, so we use 'le' as the indirect object pronoun.
