To describe a situation with a clear sky and presence of sun, which phrase would be used?

The phrase "It's sunny" effectively describes a situation where the sky is clear and the sun is present. This phrase indicates that the sun is shining brightly and contributes to a pleasant and bright environment. A sunny day typically implies good weather, which is characterized by minimal cloud cover and an abundance of sunlight. In this context, using "sunny" directly associates the conditions with the clear sky and the warmth that often accompanies sunlight.

The other choices do not accurately describe a clear sky with the presence of the sun. While "it's hot" could sometimes occur on a sunny day, it doesn’t specifically capture the essence of sunlight and a clear sky. Similarly, "it's raining" and "it's snowy" indicate cloudy or adverse weather conditions that conflict with the idea of a clear sky. Thus, "it's sunny" is the most fitting and contextually appropriate choice to depict this scenario.
