• B. When Earth is between Sun and Moon.
• C. When Moon is between Earth and Sun
• D.
  When Sun, Earth and Moon are not in the same line

Answer 1

The correct option is B When Earth is between Sun and Moon.

A lunar eclipse occurs when Earth crosses between the Moon and the Sun, which casts a shadow of Earth onto the Moon. It occurs only on full Moon day but not on every full Moon day because the Moon's orbit around the Earth is tilted relative to the Earth's orbit around the Sun. When the Moon in just the right position to pass through the Earth's shadow there is a lunar eclipse.
