Answer: The right answer is the A) Tienes paciencia.
Explanation: Just to elaborate a little on the answer, it can be added that "eres paciente" means "you are patient." The phrase "tienes paciencia" means "(you) have patience," so that is the correct choice. "Tiene paciencia" refers to he/she ("él/ella") or "usted," whereas "tienen paciencia" refers to they ("ellos") or "ustedes." Finally, "tiene paciencia" means "I have patience."
