Correct option is B
The correct option to fill in the blank is
(b) devolved.
Explanation: “Devolve into” means
to deteriorate/degenerate into something worse. The sentence implies that without intervention, the discussion would have
worsened into a bitter deadlock (“acrimonious stalemate”). Thus, “devolved into” is the best contextual fit. (Hindi meaning:
बिगड़ जाना/पतित हो जाना)
Example: The debate quickly
devolved into personal attacks.
Explain why other options are incorrect:
·
(a) evolved: means
developed/improved gradually—opposite to the negative outcome described.
·
(c) emerged: means
came out/appeared; it doesn’t collocate well with “into a stalemate” here.
·
(d) absorbed: means
taken in; “absorbed into a stalemate” is illogical.
