Explanation:

Let’s break it down:

- Option 1: December 24

That’s the day India observes National Consumer Day. The main aim? To make people aware of their rights as consumers and mark the passing of the Consumer Protection Act in 1986.

- Option 2: December 31

That one closes out the year, sure, but it isn’t connected to any official consumer celebration.

- Option 3: January 15

No relation to National Consumer Day. No major consumer events fall on this date in India.

- Option 4: March 20

That’s not it for India. Globally, World Consumer Rights Day is marked on March 15, so this one’s off too.

- Option 5: None of these

We’ve already got the answer above—so this is just a decoy.

So, the real deal is December 24.
