The rains have set . . . . . . . .? A. in B. of C. on D. out

in
of
on
out

The correct answer is: in.

The rains have set in means that the rains have started and are expected to continue for some time. The other options do not make sense in this context.

  • A. in: The rains have set in means that the rains have started and are expected to continue for some time.
  • B. of: The rains have set of does not make sense.
  • C. on: The rains have set on does not make sense.
  • D. out: The rains have set out does not make sense.

I hope this helps! Let me know if you have any other questions.
