Final answer:
The correct answer is C. Escríbelo.
Step-by-step explanation:
The correct answer is C. Escríbelo.
In this sentence, the speaker is saying, "I don't want to forget your phone number." The verb "escribir" means "to write." Since the speaker is asking someone else to write down the phone number, the appropriate form is "escríbelo," which is the command form of the verb.
For example, if you want to say, "Write it!" or "Write them!" in Spanish, you would use the command forms "escríbelo" or "escríbelos."
