Under Article 311(2), which of the following is NOT an exception where the safeguard of inquiry before dismissal can be dispensed with? 

Article 311(2) provides three specific exceptions where the safeguard of holding an inquiry before dismissal, removal, or reduction in rank can be dispensed with: (a) where a person is dismissed on the ground of conduct which has led to a criminal conviction; (b) where the disciplinary authority is satisfied that for recorded reasons it is not reasonably practicable to hold an inquiry; and (c) where the President or Governor is satisfied that in the interest of State security it is not expedient to hold an inquiry. Completion of a specified period of service is not an exception-no such provision exists. These exceptions have been strictly construed by courts.
