The correct answer is B) Crusoe enjoys building a "nation" after having been alone for so long.
The best inference about this excerpt is Crusoe enjoys building a "nation" after having been alone for so long.
When Robinson Crusoe refers to “My island was now peopled, and I thought myself very rich in subjects”, he is making a reflection on the condition of the Island after all those years of being alone. When Crusoe says “…my people were perfectly subjected; I was absolute lord and lawgiver…”, he also reflects on the personal belief that he is building a “nation” with all the elements that need to exit in such one.
