Fill in the blank with the correct option.

Most of the guests arrived for the concert ________ bus.

by

The correct answer is Option (1) - by

Most of the guests arrived for the concert ___by_____ bus.

Explanation

By : is the most common preposition used to indicate the means of transportation. In this case, the guests used buses to get to the concert.

With: suggests accompaniment or possession. It wouldn't be natural to say "with buses" unless the guests brought their own buses.

From : indicates origin or source. While the buses might have come from a specific location, that's not the key detail here.

Through:  suggests passage or means of achieving something. It's not typically used with transportation in this way.

Therefore, "by bus" is the natural way to express how the guests arrived for the concert.
