What is created as a result of Earth's shadow during a lunar eclipse?

During a lunar eclipse, Earth moves directly between the Sun and the Moon, causing Earth's shadow to be cast upon the Moon. The correct choice reflects that the shadow can appear as a dark red hue on the Moon's surface. This phenomenon occurs due to Rayleigh scattering of sunlight through Earth's atmosphere, which filters the light and allows the longer wavelengths (like red) to pass through while blocking shorter wavelengths. As a result, the Moon can appear a reddish color, often referred to as a "blood moon." This effect is particularly pronounced during a total lunar eclipse, when the entire Moon passes through the darker part of Earth's shadow, known as the umbra, leading to the observed color change.
