Islands and coastal regions experience milder temperatures compared to inland areas primarily due to the properties of water. Water has a high specific heat capacity, meaning it can absorb and retain heat energy for longer periods. This allows large bodies of water, like oceans and seas, to moderate temperatures in nearby areas.

During the day, water heats up more slowly than land, which means that coastal areas do not reach the same high temperatures that inland areas might experience. Conversely, at night, water also cools down more slowly than land, which prevents coastal areas from becoming as cold as inland regions. This moderation effect of water results in a more stable and milder temperature range throughout the day and night, compared to the more extreme temperature fluctuations found inland.

The other options, while mentioning related concepts, do not effectively explain the primary reason for the temperature differences. For instance, while land does heat and cool faster than water, this fact alone doesn't account for the overall milder climate in coastal regions. Sea breezes and humidity levels can influence local weather but are not the primary drivers behind the milder temperatures observed in these areas.
