option c

Explanation:

As per the doppler's effect, when an object in the universe move at a fast speed away from the observer, its possesses a high wavelength as compared to its original wavelength.Since red light has the highest wavelength, any object's wavelength moving towards a high values is said to be red shifted.As per the doppler's effect, when an object in the universe move at a fast speed away from the observer, its possesses a high wavelength as compared to its original wavelength.Since red light has the highest wavelength, any object's wavelength moving towards a high values is said to be red shifted.Thus, the higher the wavelength, the lower will be the frequency of an object and hence it moves at a faster speed away from the observer and hence the universe is said to be expanding.As per the doppler's effect, when an object in the universe move at a fast speed away from the observer, its possesses a high wavelength as compared to its original wavelength.Since red light has the highest wavelength, any object's wavelength moving towards a high values is said to be red shifted.Thus, the higher the wavelength, the lower will be the frequency of an object and hence it moves at a faster speed away from the observer and hence the universe is said to be expanding.Thus, option C is correct.hope help

La olla es de metal por que se calienta mas rápido, y las manijas son de madera por que así no se calientas y tienden a estar mas frías.
