Select the option which is a valid assumption for the following statement.
Statement:
The Delhi government had imposed a complete ban on the use of firecrackers in the last Diwali due to pollution.

Correct option is D

Explanation:

The statement clearly mentions that the Delhi government imposed a complete ban on the use of firecrackers during Diwali due to pollution. The reason for this action is the negative impact firecrackers have on air quality and pollution levels.

Assumption:

Option D logically follows because it directly addresses the cause of pollution (the burning of crackers) which the government aimed to reduce by imposing the ban. The smoke produced by firecrackers increases pollution, which supports the government's decision.

Other options:

Option A: While burning firecrackers might be considered inauspicious by some, the statement focuses on pollution as the reason for the ban, not religious beliefs.

Option B: This may be a possible preference, but the statement doesn’t suggest that people prefer only lights; it’s about reducing pollution.

Option C: This is unrelated to the actual reason for the ban. It focuses on children's preferences but does not address the pollution issue, which is the central concern in the statement.

Thus, Option D is the valid assumption.
