Answer and explanation

Correct answer: D. The children's toys were tidied away.

  1. Step 1: 'Children' is already plural, so possession is shown by adding 's.
  2. Step 2: The correct form is children's.
Answer
The children's toys were tidied away.
Why not the others: 'Childrens'' puts the apostrophe after an extra s, 'childrens' has no apostrophe at all and the sentence 'The children's' toys were tidied away.' has two apostrophes.
