Which of the following would you be least likely to say in response to the question: ¿Fuiste a la playa ayer?

¿Fuiste a la playa ayer? means “Did you go to the beach yesterday?” Studying very well is not a likely activity to mention as something you did at the beach, while getting lots of sun and swimming in the sea fit the setting. So “Sí, y estudié muy bien” is the least likely response.
