Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
In catalytic reforming process high octane number reformate is formed which is a main component for motor, fuel, aviation gasoline or aromatic rich feedstock. The noble metals platinum and rhenium are the catalysts used on a silica or silica- alumina support base. Fresh catalyst is chlorinated prior to use. Noble metals provides the sites and not chlorinated alumina.
