Read the following passage carefully and answer the question given below:

Last year, the government notified new rules regarding the unmanned aircraft systems/vehicles. The "liberalised drone rules" are aimed at reducing paperwork, cutting the red tape and facilitating the government's vision to make India the global drone hub by 2030. The use of drones-as-a- service in sectors like agriculture, mining, infrastructure, surveillance, emergency response, transportation, photography and videography, geospatial mapping, defence, and law enforcement is being encouraged. In sectors like e-commerce, retail and health, drone technology is being seen as a game changer in the last-mile delivery of goods. Delhi Police has also been frequently using drones in monitoring law and order of late. A separate unit for drones is also being planned. When asked about the new regulations in place, senior aviation and police officers said that all drones must be registered with the DGCA, and operators must have a licence to fly them. A fine of up to one lakh rupees can be levied on violations.

"Registrations can be done on the 'Digital Sky' platform operated by the DGCA, which is a single- window online platform for drone approvals. The operators must be over 18 years of age and trained from a DGCA-approved institution," an official said. According to the new rules, a drone operating licence, issued on the basis of a remote pilot certificate, is valid for 10 years and a certificate is not required for operating nano drones (weighing <250 grams) and non-commercial micro drones (<2 kg). The fee for a remote pilot licence fee has been reduced from Rs 3,000 (for large drone) to Rs 100 for all categories of drones.

"The ministry of civil aviation has also developed an interactive airspace map on Digital Sky with areas coded as green, yellow and red. No permission is required to fly drones in the green zones, yellow zones are controlled airspace needing permission and red are no fly zones," said another official privy to the developments.

Drones are used by the Delhi Police to:

monitor law and order

The correct answer is Option (2) → monitor law and order

The reason for selecting option (2), "monitor law and order," as the purpose for which the Delhi Police uses drones is stated in the passage. Specifically, the passage mentions that "Delhi Police has also been frequently using drones in monitoring law and order of late." This statement directly indicates that the Delhi Police uses drones for monitoring law and order.
