Detailed Solution

The assertion is correct, but the reason is incorrect.
Assertion: A lunar eclipse can only take place on a full moon night. However, because Earth's orbit around the sun and the moon's orbit around the Earth are not in the same plane, they do not occur every full moon night. Only when the sun, the Earth, and the moon align in a straight line does an eclipse occur.
Reason: When the Earth places itself between the sun and the moon and casts its shadow on it, a lunar eclipse takes place. The moon rises in the east on the night of a full moon after the sun has set in the west. The sun and moon are on opposite sides of the Earth on such a night. The moon is not visible to us because its surface is covered by the Earth's shadow. As a result, although the claim is true, the justification is false.
