Correct answer: C — Advanced (deep) caries

Caries classification by depth: incipient (within enamel or outer dentin), moderate (extending into dentin but less than halfway to the pulp), and advanced/deep (extending more than halfway through the dentin toward the pulp). Advanced caries without symptoms indicates the pulp has not yet undergone irreversible damage but requires prompt treatment to prevent pulpal involvement. Indirect pulp capping may be considered if the deepest caries over the pulp is remineralisable.
