Answer:
I think the answer is C (Spain) because in Cuba they call a bus the word 'guagua' which for Cubans means bus. In Argentina they call a bus Colectivo (English: collective bus) whereas in Spain just calls a bus 'la guagua' in the Canary islands but everywhere else in Spain it's called 'bus' or 'autobus' so I feel like Spain would be the closest answer I guess?
