Answer
View full question & answer→(C) A is true but R is false.
Explanation :
Hydrogen peroxide is a highly reactive metal that can react with light or heat to produce water. It decomposes into water and oxygen in the presence of sunlight. To prevent this reaction with light and heat it is stored in coloured bottles so that light cannot pass through it. Thus assertion is true, but reason is false.
