Select the segment which has a grammatical error in the given sentence. If there is no error, select 'No error'.
I read a novel by Sydney Sheldon within my illness.

Correct option is A

Option (a) contains an error.
The phrase "within my illness" is incorrect for describing the time period during which the novel was read. The appropriate preposition would be "during," making the correct phrase "during my illness."
· Grammatical rule used: The preposition "during" is used to indicate a period or range of time in which something happens, while "within" is typically used to express something happening inside a certain limit or area.
· Example: She learned to play the piano during her recovery from surgery, correctly using "during" to indicate when the activity took place.
