$\huge {\mathfrak {ANSWER} }$....♥️

Children love to play with toys. Isn't it ?

Answer 2

The answer is: What children love to play with?

The assertive sentence has been converted in to an interrogative sentence.

The new sentence has been written with the question mark at its end.

Here the question has been framed in a way that the original sentence functions as the answer of the question formed.  

The sentence structure has been changed keeping the tense same as the original.
