The correct answer is (b) Certiorari.
A writ of certiorari is a discretionary writ issued by an appellate court to an inferior court to review a case. The writ is used to bring a case before the appellate court for review, and the appellate court has the discretion to grant or deny the writ.
A writ of mandamus is a court order that compels a government official or other person to take a particular action. The writ is used to enforce a legal right or to compel a person to perform a legal duty.
A writ of prohibition is a court order that prohibits a lower court from proceeding with a case. The writ is used to prevent a lower court from violating the law or from exceeding its jurisdiction.
A writ of quo warranto is a court order that asks a person to show by what authority they are holding a particular office or position. The writ is used to challenge the right of a person to hold an office or position.
In the case of the question, a writ of certiorari is issued during the pendency of proceedings in a court because it is a discretionary writ that can be used to bring a case before the appellate court for review. The other writs are not issued during the pendency of proceedings in a court.
