Odd-Man Out:

The odd-man out in this set is option 'A' which is "Freeze".

Explanation:

1) Freeze:
- Freezing is the process of turning a liquid into a solid by reducing the temperature below its freezing point.
- It involves the formation of ice crystals and the solidification of the substance.
- In cooking, freezing is typically used for preserving food or preparing ingredients for future use.

2) Simmer:
- Simmering is a cooking technique that involves cooking food in a liquid at a low temperature, just below boiling point.
- It is often used for slow cooking, allowing flavors to meld together and ingredients to become tender.
- Simmering can be used for soups, stews, sauces, and other dishes that require gentle cooking.

3) Bake:
- Baking is a dry heat cooking method that involves cooking food in an oven using hot air.
- It is typically used for bread, pastries, cakes, and other baked goods.
- Baking results in a browned, crispy, and flavorful exterior while retaining moisture inside.

4) Boil:
- Boiling is a cooking technique where a liquid is heated to its boiling point, causing it to rapidly vaporize and form bubbles.
- It is commonly used for cooking pasta, boiling vegetables, and making soups or stews.
- Boiling helps to soften and cook the ingredients quickly.

Conclusion:

The odd-man out in this set is 'Freeze' because it is the only option that involves turning a liquid into a solid through the reduction of temperature, while the other options involve cooking techniques using heat.
