Assertion (A) : The decomposition of hydrogen peroxide to form water and oxygen is an example of disproportion reaction
Reson (R ) : In the represent `E_(Fe^(3+)//Fe^(2+))` and `E_(Fe^(3+)//Fe^(2+)) Fe^(3+)//Fe^(2+)` and `Cu^(2+)//Cu` are redox couples

Options

A. both a and r are ture and r is the correct explantion of a
B. both a and r are ture but r is not the correct xplanatio of a
C. a is true but r is flase
D. both a nad r are flase

Explanation

To analyze the assertion and reason provided in the question, we will break down the concepts step by step.

### Step 1: Understanding the Assertion
The assertion states that the decomposition of hydrogen peroxide (H₂O₂) to form water (H₂O) and oxygen (O₂) is an example of a disproportionation reaction.

**Disproportionation Reaction**: This is a specific type of redox reaction where a single substance is simultaneously oxidized and reduced.

For the decomposition of hydrogen peroxide:
