An entrepreneur has a good product but information does not reach customers clearly. Which trait is weak?

Correct answer: Communication and marketing skill

The direct answer is C: communication and marketing skill. A good product can succeed only when potential customers understand what it is, why it is useful, how much it costs and where it is available. The reasoning is: product exists; information must reach the target customer; the message must be clear; customers can then evaluate and buy it. Option C identifies the missing ability. Option A, product knowledge, may be present because the product itself is good, although knowledge must also be communicated. Option B, technical power, concerns making or operating something and does not solve the communication gap. Option D, material storage, concerns keeping supplies and is unrelated to informing customers. Thus the weakness is not necessarily product quality but the connection between product and market. Remember: a good product unseen or misunderstood may still fail; communication connects the product to the customer.
