The question asks about the form of radiations coming from the Sun. The correct answer is option 3 - light and short-wavelength infrared.

Option 1 states that the radiations from the Sun are only in the form of light. However, this is not entirely correct. While light is a significant component of solar radiation, there are other forms as well.

Option 2 states that the radiations from the Sun are in the form of light and long-wavelength infrared. While the presence of light is accurate, the statement about long-wavelength infrared is incorrect. Infrared radiation from the Sun mainly consists of shorter wavelengths.

Option 3, the correct answer, correctly identifies that radiations from the Sun are in the form of both light and short-wavelength infrared. Light refers to the visible spectrum of electromagnetic radiation, which includes colors like red, orange, yellow, green, blue, and violet. Short-wavelength infrared refers to the infrared region just beyond the visible spectrum.

Option 4 suggests that radiations from the Sun include both short and long-wavelength infrared. However, this is not accurate as the majority of infrared radiation from the Sun is in the short-wavelength range.

Therefore, option 3 accurately describes the form of radiations coming from the Sun.
