The correct option is (b).
Explanation
The "Saptarishi" is a prominent asterism (a recognizable pattern of stars) visible in the northern hemisphere. In Indian astronomy, it is associated with seven ancient sages, while in Western astronomy, it is known as the "Big Dipper" or the "Plough."- Statement 1 is Incorrect: The name "Saptarishi" is derived from Sanskrit, where "Sapta" means seven and "Rishi" means sages. Consequently, it is a group of seven stars, not twelve.
- Statement 2 is Correct: The Saptarishi is traditionally used as a navigational aid to locate the Pole Star (Polaris). By drawing an imaginary line through the two "pointer stars" at the end of the asterism's bowl and extending it northwards, one reaches the Pole Star, which indicates the North direction.
- Statement 3 is Incorrect: The Saptarishi forms a part of the Ursa Major (Great Bear) constellation. It is not part of the Orion constellation. Orion is a distinct constellation recognizable by the "Hunter" figure and the three aligned stars of Orion's Belt.
Key Takeaway: The Saptarishi comprises seven stars, belongs to the Ursa Major constellation, and serves as a celestial guide to locate the North Star.
