Choose the most appropriate meaning for the given proverb:
Let bygones be bygones.
The proverb, ‘Let bygones be bygones’ means: One should forgive people for their past mistakes and forget about unpleasant things that happened in the past. Hence, option D conveys the correct meaning.
Options A and B are incorrect because they talk about 'not forgiving and not forgetting'- which is the opposite in meaning.
Option C is incorrect as the proverb does not mean: You should never remember anything about the past and forget everything about it. Hence, this option is incorrect.
