The highlighted part is incorrect as 'grinding' is not suitable in the context of the sentence. 'Ground', as a verb, can mean 'prohibit or prevent (a pilot or an aircraft) from flying'. 'Grounding', the gerund form, should be used to make the sentence correct; so, A is incorrect. B is incorrect as 'subsequently' is an adverb and cannot qualify the noun (gerund) 'grounding'. We need to use 'subsequent' - an adjective - here. In D, the presence of 'in' is unnecessary and hence it cannot replace the highlighted part. Option C is the right answer.
