Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: The octane number which is a measure of knock characteristic of fuel is derived from a mixture of Iso-octane and Normal Heptane Reason R: The normal Heptane has the octane number as 100. In the light of the above statements, choose the most appropriate answer from the options given below

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

For octane number scale: \[ \text{Iso-octane} \rightarrow 100 \] \[ \text{Normal heptane} \rightarrow 0 \] Higher octane number means better anti-knocking property in SI engines.

Answer 1

The Correct Option is C
