Matching the physical quantities with their appropriate units:
A. Distance – 3. Light year (A light-year is the distance light travels in one year, used for astronomical distances).
B. Amount of material – 1. Mole (The mole is the SI unit for amount of substance).
C. Amount of electrical charge – 2. Coulomb (The Coulomb is the SI unit for electric charge).
D. Energy – 4. Watt hour (A watt-hour is a unit of energy, calculated as power (Watts) multiplied by time (hours). It is commonly used for measuring electrical energy).
This results in the sequence 3 1 2 4, which matches option A.

Matching common physical quantities with their standard or relevant units.

Other common units for distance include meters, kilometers, miles, etc. Other common units for energy include Joules (the SI unit), calories, kilowatt-hours (1 kWh = 1000 Wh). The units provided in List II are all valid units for the corresponding quantities, although some are not SI units (like light-year or watt-hour).
