2. Suppose R is a relation on a set A, and that B c A. Prove: (a) Define what it means for b E B to be an R-maximal element of B. (b) Define what it means for b E B to be an R-largest element of B. (c) Show that if b E B has a R-largest element, this element is unique. (d) Show that if b E B is the R-largest element of B, then b is an R-maximal, and b is the only R-maximal element of B
