The correct option is B withdraw proceedings as of right, and further to claim that they shall not be continued
Public Interest Litigation is a judicial innovation that relaxes the rule of Locus Standi (right to sue). It allows any public-spirited person or organization to file a suit against any wrongdoing in the interest of people who are getting affected. It is inappropriate once PIL is filed and jurisdiction of the court is invoked to withdraw the petition, as it would discourage the actual motive behind the concept that is public justice and would show the incredibility on the part of the petitioner while wasting the time of the court.
