B one is electrolytic decomposition reaction

Answer 2

Mate.......☺☺✌☺☺

✔ In first reaction the product are formed when heat is supplied to the reactant to let it breakdown .
THERMAL DECOMPOSITION


✔ And in second there is the use of electricity i.e. electrolysis process is applied to the reactant to get the required products.
ELECTRICAL DECOMPOSITION


I HOPE U UNDERSTAND..
IF IT IS HELPFUL. PLZ MARK BRAINLIEST...☺☺✌☺☺
