What is the correct meaning of the word pair 'अमित - अमित' (Amit - Ameeth)?

The word 'अमित' (Amit) means immeasurable, boundless, or a lot/excessive (Adhik/Bahut). The word 'अमीत' (Ameeth) is formed by adding the negative prefix 'अ-' to 'मीत' (friend), which means enemy (Shatru). Therefore, the correct pair of meanings is Bahut - Shatru (or Adhik - Shatru, represented accurately here by option D).
