Explanation

Six Sigma is a data-driven methodology specifically designed to give businesses a structured framework for improving process capability by reducing defects and variation - it directly matches the definition given. Design of Experiments (A) is a statistical technique for identifying cause-and-effect relationships in experiments, not a broad business improvement methodology. Benchmarking (B) is about comparing your performance against industry standards or competitors, not improving process capability itself. Failure Mode and Effects Analysis (D) is a risk analysis tool used to identify potential failure points in a process, not a comprehensive improvement methodology.

Memory tip: Think of the phrase "Six Sigma = Six Steps to Superior processes" - the name itself implies a high standard of process performance (3.4 defects per million opportunities), making it the go-to answer whenever a question asks about improving business process capability.
