Correct answer: c) Big Dipper / Ursa Major.
Why it is correct
Merak (β Ursae Majoris) and Dubhe (α Ursae Majoris) are the two ‘Pointers’ of the Plough / Big Dipper (Ursa Major); extending the line from Merak through Dubhe about five times their separation leads to Polaris.
Why the others are not
- a) Cassiopeia forms a W or M on the opposite side of Polaris.
- b) Ursa Minor contains Polaris itself and Kochab.
- d) Orion is an equatorial constellation (with Betelgeuse, Rigel and the Belt).
How to work it out in the exam
- Merak and Dubhe: Pointers of Ursa Major (5× their distance → Polaris).
