In the given sentence, we need to identify the component with a grammatical error based on the options provided.
- I. He is capable at
- II. twisting any fact
- III. without any suspicion
- IV. at any time
Let's analyze each component:
- I. He is capable at: The phrase 'capable at' is incorrect in standard English usage because the correct preposition that follows 'capable' is 'of', not 'at'. Therefore, it should be 'capable of'.
For example: 'He is capable of solving the problem.' - II. twisting any fact: This component is grammatically correct as it clearly indicates the action of twisting facts.
- III. without any suspicion: This component is free of grammatical errors and logically follows the idea of acting without raising suspicion.
- IV. at any time: This phrase is correct and effectively conveys the sense of flexibility or unpredictability in timing.
Thus, the component with the grammatical error is Only I, as it incorrectly uses the preposition 'at' instead of 'of'.
