Which are examples of religious groups?

The selection of St Vincent de Paul and the Salvation Army as examples of religious groups highlights their foundational ties to Christian values and missions. Both organizations are deeply rooted in faith-based principles and focus on serving others, particularly in need. St Vincent de Paul is known for its commitment to helping the poor and disadvantaged, while the Salvation Army combines social services with evangelism, aiming to meet both the physical and spiritual needs of individuals.

In contrast, the other options consist of organizations that do not primarily focus on religious objectives. Charity Water and the Red Cross mainly concentrate on humanitarian efforts, such as providing clean water and emergency relief, respectively. The Sierra Club and Greenpeace are environmental organizations dedicated to conservation and ecological issues, while the American Medical Association and the National Education Association represent professional interests in healthcare and education, without a religious framework guiding their missions. Thus, B represents entities explicitly designed around religious principles and outreach.
