The right answer is : C.making many religions the same under one heading or label
Religious pluralism generally refers to the belief in two or more religious worldviews as being equally valid or acceptable. More than mere tolerance, religious pluralism accepts multiple paths to God or gods as a possibility and is usually used in contrast with “exclusivism,” the idea that there is only one true religion or way to know God.
While religious pluralism has been in existence since at least the seventeenth century, the concept has become more popular since the latter half of the twentieth century in Western Europe and North America. Specifically, the idea of religious ecumenism (religions working together as one) and the recently popularized interfaith movement have led to the increased acceptance of religious pluralism in popular culture.
