Explanation:

To determine the components installed on a PC motherboard before it's placed in the case, we analyze each option:

• Power supply: Installed in the case, not on the motherboard. Eliminate.
• CPU: The CPU (processor) is installed in the motherboard's CPU socket before the motherboard is placed in the case. Include.
• Adapter cards: These are often installed after the motherboard is in the case (e.g., into expansion slots). Eliminate.
• Internal hard drives: Installed in drive bays of the case, not on the motherboard. Eliminate.
• Optical drive: Installed in the case's drive bays, not on the motherboard. Eliminate.
• RAM: Random Access Memory (RAM) modules are installed in the motherboard's RAM slots before the motherboard is placed in the case. Include.
• CPU heatsink and fan: After installing the CPU, the heatsink and fan (cooling solution) are attached to the CPU on the motherboard before the motherboard is placed in the case. Include.

So the three components are CPU, RAM, and CPU heatsink and fan.
