a. Calculus. 

b. Saliva. 

c. Dental plaque. 

d. Dental stain. 

The correct answer is C. Dental Plaque. 

Dental plaque is the general term for the complex microbial community that develops on the tooth surface. Plaque is a soft, sticky film that forms on the teeth and can lead to dental caries and gum disease if not removed through proper oral hygiene practices, such as brushing and flossing. Calculus (also known as tartar) is a hard mineral deposit that can form on the teeth when plaque is not removed, and it can contribute to gum disease. Saliva is a fluid that helps to protect the teeth and oral tissues from infection, but it is not the same as dental plaque. Dental stain refers to discoloration of the teeth that can be caused by various factors, such as smoking, drinking coffee or tea, or poor oral hygiene.
