Explanation

A Pull system limits inventory by triggering production only when downstream demand signals it - nothing is made until a customer (or the next process step) "pulls" it, directly aligning output with actual demand rather than forecasts. Jidoka (A) is about building quality in by automatically stopping production when a defect is detected - it's a quality/autonomation concept, not an inventory-flow one. Takt time (C) is the rate at which products must be completed to meet demand, a pacing metric rather than a method for controlling inventory flow. Kaizen (D) refers to continuous incremental improvement in general, with no specific mechanism tied to inventory limits.

Memory tip: Think of a pull as a customer literally pulling a product off a shelf - production only refills what's been taken. If no one pulls, nothing moves.
