The Flowing Waters Worshippers ("FWW") is a religious organization. According to its religious beliefs, water is representative of the Creator's life force. As part of their worship, the FWW's members attend weekly services in which the congregants sit in a pool and praise water sources and listen to their minister's sermons. Usually, they to conduct services in public lakes to "fuse" with the Creator's liquid energy. For the past several years, they have conducted their monthly meetings in the local Pine Ridge Lake, a small lake owned and maintained entirely by the federal government. However, because of the lack of lifeguards during the off season, Congress passed a law prohibiting swimming in Pine Ridge Lake during the off season as defined in the law. An attorney representing the FWW has filed a lawsuit on behalf of that organization challenging the validity of the law on the ground that it violates the 1st Amendment to the U.S. Constitution by interfering with the free exercise of religion.

Which of the following would be the most effective argument in support of the constitutionality of the law?

Select one:

a. The prohibition of swimming within Pine Ridge Lake does not discriminate between religions and has a primarily secular effect.

b. The law is a valid exercise of the power granted to Congress under the property clause of the Constitution.

c. The use of water is not a traditional religious practice.

d. In view of the danger of drowning, the conduct of worship services in an unmonitored lake is not a reasonable religious practice.
