Yes, you are correct. The object of the preposition in the sentence is "alone". To determine the object of the preposition, you need to identify the preposition first. In this case, the preposition is "from". Then, look at what follows the preposition - "his offices". "Offices" is the noun, and since it comes after the preposition, it is the object of the preposition. So, option D, "offices," is the correct answer.

No.
