The President of a New Jersey Public School District Is

The president of a New Jersey public school district is a newfound believer in student uniforms, having read extensive research on how they lead to decreases in bullying and gang involvement, and increases in discipline and self-esteem.After getting his board to approve a uniform plan, however, he hears complaints from families of a small religious sect-an offshoot of Sunni Islam-with students in the district.They wear head coverings that do not comply with uniform policies, and often feature policy-banned local gang colors besides. The district president agrees to work with the families to develop a standardized head covering, ones that will not feature gang colors, but will satisfy religious requirements.His efforts do not placate all of the families, however, and a group of them threatens to sue the district for violation of religious freedom protections under the First Amendment.What would be the district president's best defense, of those offered below?

A) The district policy has a clearly secular purpose, as the Lemon test requires, and the president's working with the families showed that he did not want to inhibit religion here either.
B) The remaining parents are seeking government recognition for their religion, in violation of the First Amendment's establishment clause.
C) The policy does not promote the entanglement of government and religion, as proscribed under the Lemon test.
D) The district policy is allowable as a time, place, or manner restriction, under Supreme Court rulings.
