The correct answer is: E. No error
The sentence is grammatically correct and does not contain any errors. The word “as” is used to introduce a clause that describes the action of the main clause. In this case, the main clause is “the Commissioner admitted that there had been an undue delay in the setting up of an anti-narcotics cell.” The clause “as sharing crime statistics for the year 2011” describes the action of the Commissioner. The Commissioner was admitting that there had been an undue delay in setting up an anti-narcotics cell while sharing crime statistics for the year 2011.
The other options are incorrect because they contain errors. Option A is incorrect because it does not include the word “that.” Option B is incorrect because it does not include the word “the.” Option C is incorrect because it does not include the word “had.” Option D is incorrect because it does not include the word “in.”
