To determine the direction of heat flow between two objects, we need to understand that heat flows from the object with a higher temperature (hotter) to the object with a lower temperature (cooler). Let's analyze each example:

1. Example 1: Fire (hot) and Air (cool)
- Fire is hotter than air.
- Heat will flow from the fire to the air (Object 1 to Object 2).

2. Example 2: A metal at 80°C (hot) and A metal at 12°C (cool)
- The metal at 80°C is hotter than the metal at 12°C.
- Heat will flow from the metal at 80°C to the metal at 12°C (Object 1 to Object 2).

3. Example 3: The cool ocean (cool) and A material air with little thermal energy (cooler)
- Despite the ocean being cool, the air with little thermal energy is even cooler.
- Heat will flow from the ocean to the air (Object 1 to Object 2).

4. Example 4: A tool with a lot of thermal energy (hot) and unspecified cooler object
- The tool has a lot of thermal energy, indicating it is hot.
- Heat will flow from the tool to the cooler object (Object 1 to Object 2).

Given these explanations, the statement that accurately describes the flow of heat in each example is:
- Heat will flow from Object 1 to Object 2 in examples 1, 2, and 4.
- Heat will flow from Object 2 to Object 1 in Example 3.

Thus, the correct choice is:
Heat will flow from Object 1 to Object 2 in examples 1, 2, and 4, and heat will flow from Object 2 to Object 1 in Example 3.

This corresponds to the fourth option.
