AT - exact time (my office opens at 9 am), speed (she drives her at 120 km) , building& events.

Ex: I'm at home, I'm at a hotel, I'm at a party, etc.

IN - we should use it when the noun is indicating the place or area.

Ex: I'm in Chennai, she is in this room, my dad is in the USA.

I was born in Chennai at KMC hospital. But also use IN - (month, year, seasons, long periods)

ON - day, date, electronic device.

Ex: He is on the phone, on a laptop, I'm on the train.

"an hotel" is the correct grammar not a hotel.

People get very confused about these two prepositions, but there are a couple of simple tips you can use to help yourself remember how to use them.

In, as a proposition of the place is usually used to talk about the position of someone or something inside large places such as countries, continents, big cities etc.

For example:-.

She grew up in New Zealand.

At, as a preposition of place, is usually used to talk about the position of someone or something inside small and unimportant places such as villages, small towns etc.

Please explain the grammatical reason for option A.

At is used for small and unimportant things like pub, hotel, village v/s that is used to denote big thins like country continent etc.

:).

I think A is correct because instead of 'a' we should use 'an'.

According to me, the answer might be option B.

Error in B part boarding and lodging replace by board and lodging.

There is no doubt that the option 'A' is correct.

If you think the world is in my head, so it may be other.
