_______ cause discoloration of teeth in children.

Answer 1

The Correct Option is C

Tetracycline antibiotics are known to cause permanent discoloration of teeth if administered during tooth development (pregnancy, infancy, and childhood up to about 8 years of age). The tetracycline molecules bind to calcium in the teeth, leading to yellow, gray, or brown staining.
