keywords: 

{'saturation': [0, 0, 1, 0], 'saturation deficit': [0, 0, 1, 0], 'actual humidity': [0, 0, 1, 0], 'dew point': [0, 0, 2, 0], 'moisture': [0, 0, 1, 0], 'capacity': [1, 2, 4, 6], 'temperature': [0, 1, 1, 7], 'air': [1, 0, 0, 0]}

The correct answer is option-3: Both 1 and 2.

Statement 1 is correct. Saturation deficit refers to the difference between the moisture-holding capacity of air and its actual humidity. In other words, it is the amount of moisture that the air can still hold before reaching saturation. This can be calculated by subtracting the actual humidity from 100.

Statement 2 is also correct. The dew point is the temperature at which air needs to be cooled in order to reach saturation, meaning that the air cannot hold any more moisture and condensation begins to occur. The dew point is an important factor in determining weather conditions and can influence the formation of fog, dew, and frost.

Therefore, both statements 1 and 2 are accurate explanations of the concepts of saturation deficit and dew point.
