Solution

The correct option is A Both assertion and reason are CORRECT and reason is the CORRECT explanation of the assertion.
Oxidation product of alcohols depends upon the type of alcohol( primary or secondary) and not on the temperature. Primary alcohols give aldehydes and acids on oxidation with a solution of sodium or potassium dichromate(VI) acidified with dilute sulfuric acid.
