Hi, ashik,
@ashik3140 posted:Question: Can you guess where it could be?
Answer:
(a) Yes, I guess it is an airport lounge.
(b) Yes, I guess it could be an airport lounge.
(c) Yes, I guess it would be an airport lounge.
Please tell me which of these 3 answers is correct?
Sorry for all the mistakes I made
If you know that it is an airport lounge, you can use '(a)'. If you aren't sure, you can use 'b'. You can use 'c' if you want to say 'I guess it would be an airport lounge if those people were passengers waiting for their planes.'
