Final answer:
The observation by the Mumbai store manager that customers needed assistance carrying large items like ladders is an example of direct sensory perception as a source of market information. This immediate, observational input is distinct from secondary research and quantitative methods. The correct option is B. Direct sensory perception.
Step-by-step explanation:
The situation described where a local manager in Mumbai concludes that the store needs a delivery service for larger items after noticing customers carrying a ladder is an example of direct sensory perception. This type of market information source involves managerial observation of customer behavior or other market-related events that provide insights into improving business services or products.
In contrast to secondary market research, which would involve collecting data from already published sources, or quantitative research, which focuses on gathering numerical data through surveys or experiments, direct observation allows managers to perceive and interpret customer needs immediately and intuitively.
Implementing a delivery service based on this sensory input can address an unmet customer need, thereby improving customer satisfaction and potentially increasing sales. It is crucial for businesses to respond to such observations with effective solutions to maintain a competitive edge in the market.
