Detailed Solution

concept - According to the law of multiple proportions, when two elements combine to produce compounds, one element with differing masses mixes with the other element with the same relative mass in a particular ratio of whole numbers.
Energy, which is measured in the same unit as work, is transferred when we perform work. According to this law, neither new energy can be created nor current energy can be extinguished. It transforms into different forms. We can therefore state that the total amount of energy is constant.
The same components are present in a compound with different samples in the same mass proportion. The law of constant composition is the name given to this rule.
We are aware that in a chemical reaction, the quantities of reactants and products will be equal. Regarding mass, the quantity of both substances is defined. As a result, we can state that the overall mass of a chemical reaction is fixed. Only one substance will be affected at a time. The concept of matter can also be used to explain this.
Therefore, according to the law of conservation of mass, matter cannot be created or destroyed.
So, the correct answer is Option 4.
