D Correct answer
Explanation

const, volatile, and mutable are all storage qualifiers (cv-qualifiers) in C++. const indicates the value cannot be modified, volatile tells the compiler the value may change in ways not visible to the compiler (prevents optimization), and mutable allows a member variable to be modified even in a const member function.
