Select all that apply: O For any R, S, p, and P, the set I is a prime ideal of R. O For some R, S, p, and P, the set I is an ideal but not a prime ideal of R. O For some R, S, p, and P, the set I is a maximal ideal of R. O For any R, S, 9, and P, the set I is an ideal of R. O For some R, S, p, and P, the set I is not an ideal of R.
