|1. Gasoline requires more octane number for good performance of engine. Hence octane number possess high aromatics. So aromatics is desirable in gasoline.
2. Diesel requires less auto ignition temperature. At the same way good kerosene requires high smoke point.
So both need high content of paraffins.

|Gasoline needs aromatics but diesel needs paraffins.|

|Let's explain to me:
Why do you want to be undesirable Aromatics?
I think Aromatics has octane number high and gasoline need it. But Aromatics is not good for diesel because it will crease gum.

|Paraffins is right answer, because aromatic undesirable in diesel & kerosene.|

|Option C is correct.
Aromatics has undesirable in kerosene and diesel.

|Paraffins is the right answer.|

|C is the right answer because, Aromatics increases octane number for gasoline thereby required in Gasoline. Paraffins cause Knocking in Gasoline thereby, not required in Gasoline. Mercaptan and Naphthenic acids not required in Gasoline.|

Aromatics are quite undesirable in kerosene and diesel. Aromatics increases the octane number for gasoline thereby required in Gasoline. Aromatics is not good for diesel because it will create gum.
Paraffins cause Knocking-in Gasoline thereby, not required in Gasoline.
