Final answer:
Canada's constitution is based on the Canadian Charter of Rights and Freedoms and British Common Law.
Correct option is d.
Step-by-step explanation:
The principles that form the basis of Canada's constitution are Canadian Charter of Rights and Freedoms and British Common Law. The Canadian Charter of Rights and Freedoms, enacted in 1982, guarantees fundamental rights and freedoms to all Canadians. It includes elements such as freedom of speech, religion, and association, as well as equality rights and the right to democratic participation. British Common Law, on the other hand, refers to the legal system inherited from the British colonial period, which forms the foundation of Canada's legal system.
