Which gear range should I choose for Indian city and hill riding?

The 11-34T provides the best versatility for Indian conditions — 11T gives sufficient speed on flat roads and 34T makes steep Indian hills manageable. Choose 11-32T if your rear derailleur cannot accommodate 34T.

Is the HG-31 compatible with a 7-speed drivetrain?

No — the HG-31 is an 8-speed cassette and must be paired with an 8-speed chain, shifter, and rear derailleur. For 7-speed, you need the CS-HG21 or similar 7-speed cassette.

Can I upgrade to a wider range without changing my derailleur?

It depends on your derailleur's maximum sprocket capacity. Check the derailleur specifications — an Altus RD-M310 supports up to 34T, making the 11-34T HG-31 compatible.
