She . . . . . . . the two candles in one breath.

put down
put up
put away
put out

The correct answer is D. put out.

The other options are not correct because:

  • A. put down means to place something on a lower surface.
  • B. put up means to raise something to a higher position.
  • C. put away means to store something in a safe place.

In the sentence, “She put out the two candles in one breath,” the word “put out” means to extinguish a fire. This is the most logical interpretation of the sentence, given the context.
