Over time, products wear out and break down.

Over time, products wear out and break down.

• A. Innovation
• B. Diffusion (Markets)
• C. Disruptive innovation
• D. Functional obsolescence

Answer: (D)

The main idea is that a product loses its ability to perform its intended function as it ages and wears out. This is functional obsolescence: the item still exists, but components wear, parts break, and performance declines, making it less effective or reliable for its purpose. It isn’t about how quickly a new product spreads through the market, nor about a new product disrupting the market, nor about creating something new. Those other terms describe market adoption or innovation, not the declining function of an aging product.
