Relative humidity is defined as the ratio of the actual vapor content in the air to the maximum vapor content the air is capable of holding at a given temperature. This ratio is expressed as a percentage, and it represents the saturation level of the air. Answer D accurately captures this definition, while the other options do not fully describe relative humidity.
Option A is incorrect as it does not mention the air's vapor holding capability. Option B is incorrect as it refers to the maximum vapor content, not the ratio to the actual vapor content. Option C is incorrect as it refers to the minimum vapor content, which is not how relative humidity is defined.
