Respuesta :
Answer:
b. vaya
Explanation:
Vaya is the subjunctive form of the verb 'ir' (go).
The subjunctive verb tense in English, isn't similar to the one in Spanish, but you can approximate it with "could".
The sentence would read as follows:
"Ojalá que yo vaya a la playa con él."
Which means
"Hopefully I could go to the beach with him."
