Which of the following is the correct order for the processes used to obtain petrol from
petroleum (crude oil)?
A Petroleum > fractional distillation > reforming > petrol.
B Petroleum > reforming > fractional distillation > petrol.
C Petroleum > reforming > fractional distillation > petrol.
D Petroleum > fractional distillation >reforming > petrol.
answer is C but it makes no sense to me. Why reform before distilling. I thought it was D.

Technically aren't A D and BC the same options?

You're right first we obtain petrol from crude oil and then cracking and reforming is done
