Hey there!
Well, a compound noun is a noun but with two words combined.
Clap - This is just one word, and it is a verb not a noun.
Homework - This is two words, (the word "home" and work") and it is a thing meaning it is a noun. This should be correct.
Lazy - This is an adjective because it is describing someone and it is also just one word.
The correct answer to your question is option B) Homework.
"Homework" is the compound noun.
Hope this helps you.
Have a great day!
