Asslam-o-Alaikum LNaqvi,
It is one of the analytical questions which you have asked.
As "Criminology" is a new subject, included in the revised syllabus. I don't think that the FPSC will ask "What is Criminology in the Islamic perspective", the major reason behind my observation is that the 'said question' pertains to Islamic Law subject. Moreover, there's not any such type of thing is mentioned in the syllabus. I recommend you to completely grasp upon mentioned topics of the syllabus. Hopefully, you'll up to the mark.
Regards,
Afaque Ahmed.
