Asap! you : ) which of the following could replace the word 'it' in the sentence as a correct noun clause? it is a mystery. a. how to dance gracefully b. where driving c. under the sun d. how the baby sleeps with all the noise

Hello!

I believe the correct answers for this question would be: A. How to dance Gracefully, and D. How the baby sleeps with all the noise. Here is how they would all look:

How to dance gracefully is a mystery.
Where driving is a mystery.
Under the sun is a mystery.
How the baby sleeps with all the noise is a mystery.

So, judging by these sentences, I feel those two would only be the appropriate choice.

I really hope this helped you out! :)
