Final answer:
The TEMP register in the 8085 microprocessor holds one of the 8-bit ALU operands and is connected to the internal data bus bi-directionally.
Step-by-step explanation:
The TEMP register in the 8085 microprocessor holds one of the 8-bit ALU operands. It represents a temporary storage location for data during the execution of instructions. The TEMR register is connected to the internal data bus bi-directionally, which means it can send and receive data to and from other parts of the microprocessor.
