The writer is considering deleting the phrase “which became a required piece of equipment in any dentist’s office” from the preceding sentence (ending the sentence with autoclave). Should the phrase be kept or deleted?

A. Kept, because it emphasizes the universal importance of the device in modern dentistry.
B. Kept, because it clarifies the term autoclave and contributes to the logic of the paragraph.
C. Deleted, because the paragraph has already stated that modern dentist offices had become more sterile.
D. Deleted, because it draws attention away from teeth and places it on equipment.
