Why are line extensions more common than new products? a) They are higher risk and more expensive. b) They are guaranteed to succeed in the marketplace. c) They are less expensive and lower-risk. d) They require no market research. e) Modifications to existing products are very easy

The answer is c) : They are less expensive and lower-risk.

Step-by-step explanation:

Line extensions are more common than new products because they do not require an overhaul of old or existing products or marketing strategies: old/existing products only have to be changed, and this requires lesser money, and is less risky. On the other hand, creating new products is more expensive and risky than line extensions.
