The correct version of the sentence that corrects the error in the compound adjective is B. Millie might not be able to attend the play tonight because she still has to find someone to watch her two-year-old daughter for the night

The correct version of the sentence that fixes the error in the compound adjective is:

B. Millie might not be able to attend the play tonight because she still has to find someone to watch her two-year-old daughter for the night.

To understand why this is the correct version, we need to look at the compound adjective "two-year-old." In compound adjectives, when we are using multiple words to describe a noun, we usually use hyphens to connect those words together. This helps to clarify the meaning and avoid any confusion.

In this case, we are describing Millie's daughter as being "two-year-old." Instead of writing it as "two year old," which creates confusion and doesn't show that the words are connected, we should use hyphens to connect these words together: "two-year-old."

So, the correct version is "two-year-old daughter." Option B correctly uses hyphens to form the compound adjective, fixing the error in the original sentence.
