Apu and Durga are characters from the novel "Apu Triology" and film "Pather Panchali" created by Bibhutibhushan Bandyopadhyay (also spelled as Mukhopadhyay). The Bengali author wrote these famous works that became part of Satyajit Ray's acclaimed Apu Trilogy films. While the spelling in option B shows "Bandyopadhyay," this is an alternative spelling of the same surname, making it the correct answer.
