The paths of glory lead ...... to the grave.

Solution (By Examveda Team)

The paths of glory lead but to the grave.
In this context, the word "but" is used to convey a contrast or contradiction. The phrase suggests that despite the pursuit of glory or fame in life, ultimately, everyone meets the same fate - death. Therefore, "but" is the most appropriate choice to complete the sentence, emphasizing the inevitability of mortality despite any achievements or successes in life.
