The answer is B, podia.
The sentence means:
Two years ago, I couldn't swim, but now I can.
The word that best fit in the sentence was podia, which means couldn't.
Glad to help :-)
According to 3 translation apps they all translate to the same thing. So pick one I guess :)
Querida Sabrina,
estoy en el hospital, tengo que estar aquí dos días más. Acabo de sacar los tonnsils. Los doctores dijeron que tenía que permanecer para la observación para asegurarse de que la cirugía salió bien. Es tan aburrido estar sentado aquí, en esta habitación. Desearía que estuvieras aquí pero sé que estás demasiado ocupado con tus clases. Divertirse en la escuela y tener juegos de voleibol que tengo que perder. ¡No puedo esperar a verte el jueves! Dile a todos que yo también los extraño. Y diles que me envíen comida. Van a conseguirme grasa. De todos modos, ¡te echo de menos chicos! PD Principalmente usted!Tu amigo,
