Assume that op 1 and op 2 be two Boolean operations. Let, middot, and + denote the three common Boolean operations, complement, multiplication and addition, in that order. Which of the following statements imply that op 1 and op 2 form a functionally complete set for all Boolean functions? {op 1, op 2} is a subset of}. The complement and multiplication operations can be expressed using only op 1 and op 2. The input/output tables for op 1 and op 2 are different. {op1, op2) is disjoint from}
