Match List-I with List-II:
| List-I | List-II | ||
|---|---|---|---|
| A | Kepler's First Law | I | \( \frac{\Delta A}{\Delta t} = \text{constant} \) |
| B | Kepler's Second Law | II | \( T^2 \propto a^3 \) |
| C | Kepler's Third Law | III | Measurement of \( G \) |
| D | Cavendish Experiment | IV | Elliptical orbits with Sun at one focus |

Correct answer · Option 2
A-(IV), B-(I), C-(II), D-(III)
Explanation
Kepler's 1st law is the Law of Orbits (IV), 2nd law is the Law of Areas (I), 3rd law is the Law of Periods (II), and Cavendish experiment measured \( G \) (III).
