Final answer:
The description of the land purchased by Bobby the Buyer, using landmarks like trees and boulders, indicates that the method of land description is Metes and Bounds (Option C).
Step-by-step explanation:
Bobby the Buyer purchases a lot for his dream house and, given the land description provided, the method of land description in question is C) Metes and Bounds. This system involves using natural landmarks such as trees, boulders, and streams to describe the boundaries of a parcel of land. The description given, mentioning a Tulip Tree, the banks of Jeremy's Run, two Oak trees, and two large boulders, is typical of this system.
Metes and bounds was introduced by English settlers and was predominant during the colonial era. It has been characterized by its use of local landmarks and a lack of a systematic grid, contrary to the Rectangular Survey System, which involved a rectangular grid and standardized plot sizes as devised under the leadership of Thomas Jefferson to stimulate orderly settlement and the creation of a middle class of yeoman farmers.
