The question asks which word corresponds to the Bengali term 'সেকেলে,' which conveys the idea of something that is outdated or no longer in common use. Among the options provided, 'Obsolete' (A) is the most appropriate choice because it specifically refers to something that has fallen out of use and is superseded by newer alternatives or lacking relevance in a contemporary context.

Let's analyze the other options:

- 'Old' (B) generally refers to something that has existed for a long time, but it does not necessarily imply that the item or concept is irrelevant or no longer used; many old items can still be functional or appreciated.

- 'Ancient' (C) denotes a time long past, specifically referring to historical periods, but does not imply obsolescence. Ancient items may still hold significant value and cultural importance.

- 'Ago' (D) relates more to time, indicating a distance from the present without the implication of being outdated or unused.

Thus, 'Obsolete' clearly aligns with the meaning of 'সেকেলে' because it captures both the age aspect and the idea of something being rendered irrelevant or ineffective over time.
