How to think about questions like this

Each stage demands different pricing, promotion, and product strategies. Questions like this test whether you can distinguish Product Life Cycle from neighboring concepts. The most common trap is choosing a closely-related concept that sounds similar but applies in a different context.

When you see a definition question on an exam, do two things: (1) translate the question into your own words, then (2) generate the answer in your own words before reading the options. This avoids the cognitive bias of recognizing a familiar phrase as correct just because it is familiar.
