Solution:Concept: In this question, we need to talk about the possibility of a lunar eclipse.
Eclipse is a phenomenon in which any body in space passes through the shadow of another body.
When earth, sun and moon are aligned in the same line and the shadow of earth generated when sunlight falls in it is projected on the body of the moon, then the phenomenon is called lunar eclipse.
The occurrence of lunar eclipse is a rare phenomenon and it occurs for a few minutes to a few hours.
So, we say that it is a less common phenomenon.
Hence, option 1 is correct.
