The Correct Option is D

Solution and Explanation

To establish the correct sentence order, a logical information flow must be determined. Each sentence's connection will be analyzed:

  1. Sentence 4: "Beacons are tiny and inexpensive, micro-location-based technology devices that can send radio frequency signals and notify nearby Bluetooth devices of their presence and transmit information." This sentence introduces beacons, serving as a suitable opening.
  2. Sentence 3: "Smart phones or other mobile devices can capture the beacon signals, and distance can be estimated by measuring received signal strength." This explains signal reception, logically following the introduction.
  3. Sentence 1: "Various industrial sectors including retail, transit systems, enterprises, educational institutions, event organizing, finance, travel etc., have now started leveraging these beacon solutions to track and communicate with their customers." This details practical applications, fitting after explaining the mechanism.
  4. Sentence 2: "A beacon fixed on to a shop wall enables the retailer to assess the proximity of the customer, and come up with a much targeted or personalized communication like offers, discounts and combos on products in each shelf." This provides a specific retail example, concluding the paragraph.

The analysis indicates the proper sentence sequence for a coherent paragraph is 4, 3, 1, 2. The correct order is 4312.
