Explanation
The correct option is C: Anson.
The statement is a quotation from Sir William Anson, a British jurist and legal historian, who wrote a famous treatise on the law of contract in 1879. Anson's definition of the law of contract reflects the classical view that contracts are based on mutual promises and expectations, and that the main function of the law is to enforce them. Anson's work has been influential in shaping the development of contract law in common law countries, such as England, India, and the United States.
