Explanation:

Here’s the thing—National Consumer Day in India is celebrated on 24th December. Let’s break down the options:

- Option 1: 26 December—not related to National Consumer Day in India at all.

- Option 2: 26 November—this is the day India adopted its Constitution in 1949, known as Constitution Day, not about consumers.

- Option 3: 24 November—nothing major linked to consumers or rights is observed on this day.

- Option 4: 24 December —this date marks the enactment of the Consumer Protection Act in 1986, which aimed to protect buyers from unfair trade practices. That’s why it's celebrated as National Consumer Day.
