The correct options are
B Ashok
C Kevin
Prostitution is a criminal offense, and any person participating in such activities, if found guilty, will face imprisonment.
So both Ashok and Kevin would face criminal charges. Kashif rescued her from the brothel so he would be the witness, while Lasya would be the victim against who the crime was perpetrated. The duration will depend on the severity of the crime, and may vary between 7 years to lifetime imprisonment. The police officer has the liberty to enter the premises or investigate the case without any warrant. The sub-inspector may enter the place where the victims are kept. The victims need to undergo medical checks. This is to determine the degree of abuse, before being produced in front of the police officer or Magistrate.
