Explanation:

- Here’s the thing: Fundamental Duties, listed in the Indian Constitution, aren’t just legal boxes to tick.

- They’re meant to remind citizens about their responsibilities, like respecting the national flag, cherishing heritage, and promoting harmony.

- The impact? It’s all about ethics—how people ought to behave, what kind of society we want, what’s right and wrong.

- Option 1 (ethical) is dead-on. The duties clearly have ethical significance.

- Option 2 (historical) doesn’t really fit because Fundamental Duties are rooted in contemporary civic life, not anchored in history.

- Option 3 (religious) is off base—they’re not tied to any single religion but apply to everyone, keeping secularism in mind.

- Option 4 (political) may sound plausible because they’re in the Constitution, but the spirit is about moral conduct, not political maneuvering.
