Answer:
B. Three
Explanation: The Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans (TCPS or the Policy) is a joint policy of Canada’s three federal research agencies. The research agencies are the Canadian Institutes of Health Research (CIHR), the Natural Sciences and Engineering Research Council of Canada (NSERC), and the Social Sciences and Humanities Research Council of Canada (SSHRC), also called the Agencies.
This Policy expresses the Agencies’ continuing commitment to the Canadians to promote the ethical conduct of research that involves human beings. It has been informed, in part, by leading international ethics norms, all of which may help, in some measure, to guide Canadian researchers, in Canada and abroad, in the conduct of research involving humans.
The policy was adopted in the year 1998.
