- A. Knowledge of consumer behaviour leads to more capital expenditure in manufacturing sector.
- B. Knowledge of consumer behaviour stimulates the growth of commerce and trade and thus helps in the overall economic development of the country.
- C. Interconnected devices give a lot of comfort to home users and improve the overall quality of life.
- D. Interconnected devices can be at security risk and home users may have privacy risk.
Answer: D
Explanation
The passage highlights a concerning trend: manufacturers and service providers of interconnected home devices will gather ‘more of our personal data—with or without our agreement—turning the home into a corporate storefront.’ This explicit mention of data collection without consent and the commercial exploitation of personal spaces strongly implies significant risks to privacy and security for home users. Options (A) and (B) discuss economic impacts that are not the primary message of concern conveyed by the passage. Option (C) presents a positive aspect of interconnected devices, which the passage does not focus on; instead, it points to the potential downsides. This question assesses the ability to infer the primary concern or warning conveyed by the text.
