Chemistry · REDOX REACTIONS

Given below are two statements: Statement I: For a combination reaction to be classified as a redox reaction, either one or both of the reacting substances must be in the elemental form. Statement II: In the combustion of methane: \( \text{CH}_4(\text{g}) + 2\text{O}_2(\text{g}) \xrightarrow{\Delta} \text{CO}_2(\text{g}) + 2\text{H}_2\text{O}(\text{l}) \), there is a significant change in the oxidation number of hydrogen. In the light of the above statements, choose the most appropriate answer from the options given below:

1. A
   Both Statement I and Statement II are correct.
2. B
   Both Statement I and Statement II are incorrect.
