Answer:
Conocer
Step-by-step explanation:
Saber and conocer both mean "to know" but in different ways. Saber means "to know information," like you know how to speak English or how to draw or what an apple is.
Conocer means "familiarity." So you're acquainted with a neighbor or the city of New York. You use the personal a with conocer when you're expressing that you're acquainted with someone.
For example, Conozco a Maria. (I know Maria).
