Option 1 -> Starts with "correct use of English" which doesn't work as an opening phrase without context.
Option 2 -> "In other words, grammar grows and changes, and there is no such thing as correct use of English for the past, present and future" - flows logically and makes complete sense.
Option 3 -> Begins with "and there is no such thing as" which is grammatically awkward as a sentence opener.
Option 4 -> Places phrases in a disjointed manner that disrupts the logical flow and meaning.
Hence, Option 2: (D), (A), (C), (B) -> This sequence correctly forms a meaningful sentence explaining that since grammar evolves over time, there cannot be one definitive "correct" English usage applicable across past, present, and future -> correct
