The Correct Option is A
Solution and Explanation
For a function to be piecewise continuous according to Dirichlet’s conditions, it must have only a finite number of extremities (maxima and minima) and discontinuities within any finite interval. This specifically excludes infinite discontinuities which would make the function not piecewise continuous.
