Which sentence must be revised to eliminate a split infinitive?

a. jacob went to band practice and came home with a sunburn.

b. lucas makes it a habit to only watch the stunts the skateboarders did.

c. emily loves to noisily and cheerfully make breakfast for her family each day.

d. samuel needs to regularly organize the papers and folders in his school bag.

b is wrong.

The correct answer is C. Emily loves to noisily and cheerfully make breakfast for her family each day.
A split infinitive refers to the fact that there is a word included between the word TO and the verb. That word should not be there because it makes the infinitive to split itself into two parts. So here, as you can see, words noisily and cheerfully make a split between the word TO and verb make breakfast, which shouldn't be done.
