• Hail Formation Microphysics:
• Hailstones develop exclusively within severe, deep convective cumulonimbus storm clouds possessing intense vertical updrafts ($\gt 20 - 30\text{ m/s}$).
• Hail embryos grow through accretion (riming) by sweeping up supercooled liquid water droplets and ice crystals in the cold, sub-freezing zone of the cloud (temperatures between $-10^\circ\text{C}$ and $-30^\circ\text{C}$, several kilometers above the cloud base).
• Incorrect Statement: Hailstones never form in the warmest base of a thunderstorm cloud where temperatures are above freezing. (Correct answer: Option 4)

• Mechanism of Tipping Bucket Rain Gauge:
• Precipitation enters a collector funnel ($200\text{ mm}$ standard diameter) and drains into a balanced two-compartment triangular bucket pivoted on a horizontal axle.
• When exactly $0.1\text{ mm}$ (or $0.2\text{ mm}$) of rainfall fills one compartment, gravity tips the bucket over, emptying the water while bringing the second compartment into position.
• Each mechanical tip actuates an electrical reed switch contact, sending an instantaneous digital pulse to an electronic datalogger/counter. (Correct answer: Option 2)

• Global Latitudinal Zonation:
• Doldrums / Equator: $0^\circ$ to $5^\circ\text{ N/S}$ (Equatorial low pressure trough).
• Trade Winds: $5^\circ$ to $30^\circ\text{ N/S}$.
• Horse Latitudes: Subtropical high-pressure belts located between $30^\circ$ and $35^\circ\text{ N/S}$.
• Roaring Forties: Strong westerly winds in the Southern Hemisphere located between $40^\circ$ and $50^\circ\text{ S}$.
• Ascending Order of Latitudes: Arranging these zones by increasing numerical latitude values gives Horse latitudes ($30^\circ-35^\circ$) followed by Roaring Forties ($40^\circ-50^\circ$).
• Conclusion: Option 3 represents the correct sequence.

Correct option: (3) (B), (A), (D), (C)
