Assume we want to build a logic circuit with 4 inputs and has 3 prime implicants. Assume the following component costs: 16-input multiplexer: 15 . 4-input decoder: 10 . AND gate (any number of inputs and any input may be a "bubble): 4 OR gate (any number of inputs): 6 What is the least expensive option for implementing this circuit? Select one: 0 a. Using the AND and OR gates, or using a multiplexer with hardcoded inputs are of equal cost and are less expensive then using a decoder and OR gate O b. Use AND and OR gates O c. Use MUX with hardcoded inputs O d. Use decoder and OR gate
