The sum-of-products expression involves creating AND gates for each product term and then OR-ing these results together. The number of AND gates corresponds to the number of product terms, the number of inputs to each AND gate corresponds to the number of variables in each term, and the OR gate combines these product terms. The number of inverters corresponds to the number of NOT operations needed on input variables. Without the specific table data, the most logical minimum setup for a generic sum-of-products expression with unspecified terms would involve AND gates for products, a single OR gate to sum them, and a variable number of inverters for NOT operations. Choice D suggests a configuration that aligns with the typical structure of a sum-of-products circuit, assuming three product terms and a need for inversion on some inputs.
