Why not A here? If this is for a large number, batchable might be of interest as well

A is incorrect. If you try declare class in this way you`ll get the error: No type arguments provided for a parameterized type: Database.Batchable. If declaration was global inherited sharing class ProcessAccountProcessor implements Database.Batchable<sObject>, Schedulable then A would be correct answer
