Question

a type of control unit in which the opcode from the instruction register is sent to the control store address register. hardwire single level microprogrammable multiprocessor two level microprogrammable

Explanation:

In single-level microprogrammable control units, the opcode from the instruction register directly maps to the address of the microinstruction in the control store, which matches the description provided. Hardwired control uses logic circuits instead of a control store. Multiprocessor refers to a system with multiple processors, not a control unit type. Two-level microprogrammable control adds an extra layer (like a microinstruction sequencer) rather than directly sending the opcode to the control store address register.

Answer:

B. Single Level Microprogrammable
