Which statement about the relationships among the Earth, sun, and moon is NOT true?

Focusing on the correct answer, the statement about the visibility of a lunar eclipse is accurate in context. A lunar eclipse occurs when the Earth is positioned directly between the sun and the moon, which is indeed when the moon is full. For option C to be true, there would need to be a specific alignment or positioning of the moon depicted in the photo, which is not confirmed in the question. More generally, the visibility of a lunar eclipse requires that the sunlight is blocked from directly illuminating the moon, which correlates with its full phase rather than an ambiguous position.

Understanding the contexts of lunar and solar eclipses highlights that some statements do not align with planetary positions. The alignment of the sun, moon, and Earth is a fundamental aspect of both solar and lunar eclipses, but the specific positioning referenced in option C may not provide the appropriate context for visibility during a lunar eclipse. Thus, this option stands out as the one that is not true.
