To determine which of the options provided is a non-renewable resource, let’s first define what non-renewable resources are. Non-renewable resources are those that do not replenish at a sustainable rate and can be depleted with usage.

1. Water: While water is scarce in some regions and can be depleted, it is generally considered a renewable resource as it cycles through nature (hydrological cycle).

2. Minerals: These are non-renewable resources because they take millions of years to form and cannot be replenished within a human timescale.

3. Air: The air is constantly replenished through natural processes, making it a renewable resource.

4. Sunlight: The sun produces energy continuously and is also regarded as a renewable resource.

Conclusion:

From the analysis above, the correct answer is b. Minerals, as they are the non-renewable resource among the options provided.
