  78% (39)
• C
  12% (6)
• D

Explanation

Kaizen is correct because it is the Lean principle specifically describing continuous, ongoing improvement - a never-ending commitment to identifying and eliminating the seven wastes (transport, inventory, motion, waiting, overproduction, over-processing, defects) at every level of an organization.

Why the distractors are wrong:

• A. Ishikawa - refers to the fishbone/cause-and-effect diagram used for root cause analysis, not continuous waste reduction.
• C. Kanban - is a visual workflow scheduling system (cards/boards) used to manage work in progress, not a philosophy of continual waste elimination.
• D. Muda - is the Japanese term for waste itself (the thing being eliminated), not the principle describing the elimination process.

Memory tip: Break "Kaizen" into its Japanese roots - Kai (change) + Zen (good) = "change for the better." If the question mentions ongoing or continual improvement, think Kaizen. If the question defines what you're eliminating, think Muda.
