B Correct answer
Explanation

The Template Method pattern defines the skeleton of an algorithm in a method, deferring some steps to subclasses. It implements invariant parts of an algorithm once in the base class while allowing subclasses to override the variable parts. This promotes code reuse and enforces algorithm structure.
