I only need help with " bitwise logical AND of two bit strings"

HW04 Q7. A programmable processor implements the Fetch-Execute cycle (text Algorithm 4.1). Fill in the table with yes or no followed by a short reason. The cell contents is to answer whether the given type of hardware unit would be expected to be part of the circuit implementing the Fetch step, the Execute step, both steps, or neither step and why you expect this. Part of Fetch step circuit? Part of Execute step circuit? Hardware unit register Part of Fetch step circuit? Part of Execute step circuit? Hardware unit bitwise logical AND of two bit strings
