Once you attempt the question then PrepInsta explanation will be displayed.
The sentence given has two errors.
The first error is the reference to “no place”. The correct word to be used in this context is “room” (as the person here looks for a space to occupy).
Place= a specific location, or a particular portion of space
Room= a portion of space, that is available to occupy or already occupied
Space= a continuous unoccupied area
Seat= place to sit
“There were no unoccupied seats” would have worked; as ‘seat’ is a countable noun, it is more natural to say “no seats” than “no seat”. Using ‘no’ combined with a singular is possible, but implies that there would only be either one of that thing, or nothing.
The second error is the use of the word “shifted”.
‘Shift’ implies a small movement or a swap; for a greater change in position, ‘move’ is the word to be used.
So the correct option is (A).
The question is \" Choose the grammatically correct option \"
Hence, the answer is option A
