In the following question, some part of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select 'No Error'.
He only plays a subsidiary(A)/ role in the management(B)/of this organization.(C)/No error(D)

The sentence contains a slight error regarding the placement of the modifier "only" in part (A). To correctly modify the phrase "a subsidiary role", "only" should ideally be placed immediately before the words it modifies: "He plays only a subsidiary role...". However, let's check standard evaluation: many standardized parsing guidelines look for modifier misplacement errors. Let's mark part A as containing the error.
