Show Hint
Whenever a question speaks about mass being perfectly preserved or remaining unaltered across a chemical reaction framework, it is always referring to the Law of Conservation of Mass.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
The question asks to identify the fundamental chemical combination law that dictates the absolute conservation of total matter during physical or chemical changes.
Step 2: Detailed Explanation:
The given statement directly represents the Law of Conservation of Mass, formulated historically by Antoine Lavoisier in 1789. This law asserts that the total net mass inside an isolated system remains entirely constant over time. Consequently, during any standard chemical transformation, the cumulative mass of the reacting molecules must exactly equal the cumulative mass of the newly formed products. Matter simply changes its bonding arrangements, meaning no atomic mass is created out of nothing or lost from the system.
Step 3: Final Answer: The correct law is the Law of Conservation of Mass, which corresponds to option (C).
