The correct answer is option 1: Both A and R are individually true and R is the correct explanation of A.

Explanation:

- Assertion (A) states that a pure piece of diamond, when burnt strongly, changes into CO2.

- Reason (R) states that diamond is made up of only carbon atoms.

Let`s break down each option to understand them better:

Option 1: Both A and R are individually true and R is the correct explanation of A

This option correctly states that both the assertion (A) and the reason (R) are true, and the reason provides a correct explanation for the assertion. Diamond is indeed made up of only carbon atoms, and when it is burnt strongly, it reacts with oxygen to form carbon dioxide (CO2).

Option 2: Both A and R are individually true but R is not the correct explanation of A

This option suggests that both the assertion and the reason are true, but the reason does not explain the assertion. However, this is not the case as the reason accurately explains why a pure piece of diamond changes into CO2 when burned.

Option 3: A is true but R is false

This option states that the assertion is true, but the reason is false. However, the reason is actually
