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.
