hen writing proofs by contradiction we begin by assuming the opposite of a statement, and then show that this leads to (ie. entaila) a contradiction. Which of the following statements constitutes a contradiction (that is, which of the following evaluates to false)? Suppose R(z,y) is a binary selation that relates two natural mumbers. Select all that apply. AO (3z e N.R(z,2) V R(z+ 1,z+ 1)) ^ (Yz. R(z,z)) B.O (Yz,y E N.R(z, y) → R(y,z) A R(3, 3) c.o (z, y E N.R(z, y) → R(y, z)) A R(3, 4) A R(4,3) D. O Vz, y, z EN.(-(R(z, y) ^ R(y, z)) V R(z, z)) A R(2,4) A R(4, 6)
