While standoffs between India and China along (A)/ the LAC have occurred in the past, the most significant (B)/ been the one in Dokhlam three years ago, but this was the first time (C)/ in over four decades that the two sides (D)/ were involved in bloodshed in the LAC (E) .
C- Here, ‘been’ should be replaced with ‘being’, as ‘been’ would indicate something that happened in the past and doesn’t stand true anymore which is not the case here. E- LAC refers to the ‘Line’ of Actual Control, therefore the preposition ‘in’ makes the sentence contextually incorrect. ‘In’ should be replaced by ‘along’. Correct Sentence: While standoffs between India and China along the LAC have occurred in the past, the most significant being the one in Dokhlam three years ago, but this was the first time in over four decades that the two sides were involved in bloodshed along the LAC.
