Final answer:
The conflict in "The Interlopers" is a family feud between Ulrich von Gradwitz and Georg Znaeym over land, rather than a gender-based conflict or feminist criticism theme.
Step-by-step explanation:
Regarding the short story "The Interlopers" by Saki (H.H. Munro), the main conflict is a family feud between two men, Ulrich von Gradwitz and Georg Znaeym, stemming from a generations-long territorial dispute over a piece of forest land. Thus, the correct answer to the type of conflict presented in "The Interlopers" is C) Family feud. This conflict does not involve direct feminist criticism, changes in family structure during societal upheavals, or typical gender roles, but instead showcases a struggle for power and property between male characters, entrenched in historical grievances that escalate to a life-threatening situation when nature intervenes.
