What will be the next term of the series?

The series follows basic logic gates in a standard pedagogical order: AND, OR, XOR are fundamental gates. The next logical gate in this progression is XNOR (the complement of XOR), but among the given options, NOR is the most plausible answer as it represents the complement series (NAND complements AND, NOR complements OR). However, if the pattern is meant to cycle through fundamental gate types in digital logic curriculum, NOR fits best as the next distinct gate operation.

Step-by-step Derivation:
The series presents fundamental logic gates: (1) AND - basic conjunction gate, (2) OR - basic disjunction gate, (3) XOR - exclusive OR gate (outputs 1 when inputs differ). The natural progression in digital electronics would continue with either XNOR (complement of XOR) or NOR (complement of OR). Among the four options provided (NAND, NOR, MNT, MPO), NOR is a legitimate logic gate and the most technically sound choice. MNT and MPO are not recognized logic gate operations in digital electronics.
