Mastering C++: A Comprehensive Quiz Based on 'Thinking in C++'

C++ provides us with casting options to explicitly convert one data type to another. Casting allows us to change the data type of a variable, typically from a larger data type to a smaller one. Type conversion operators, function overloading, and templates are all techniques used in C++, but they do not specifically deal with type conversion. Type conversion operators allow for implicit conversions, while function overloading and templates handle different data types in a more general sense. However, casting allows for precise type conversion in C++. Therefore, the correct answer is B.
