Final answer:
The correct answer is A. se lo.
Step-by-step explanation:
The correct answer is A. se lo.
This sentence means 'I give a pencil to María.' The direct object in this sentence is 'ml lápiz' (a pencil), and it is being given to María. In Spanish, the indirect object pronoun 'le' is used to indicate the person receiving the direct object. The direct object pronoun 'lo' is used to replace the direct object in the sentence. Since 'lo' refers to 'ml lápiz', it is placed before the indirect object pronoun 'le' to form 'se lo'.
