Hint: Here we can identify the type of eclipse on the basis of umbra which belongs to Earth. The earth’s umbral part plays an important role to identify whether the eclipse is total or partial.

Complete step by step solution:
We are living on earth and at present we have two most prominent astronomical objects which are named as our sun and our moon. They are nearly the same size when we see in the sky but in reality, the sun is very much bigger than the moon.
We know that there are mainly two types of eclipse.
One is caused when the earth comes between the sun and the moon. Then earth blocks the sunlight and the sunlight can’t reach the moon, then it is known as lunar eclipse
The other one is caused when the moon comes between the sun and earth. Then the moon blocks the sunlight and the sunlight can’t reach to earth, then it is known as solar eclipse
Total eclipse is caused when the earth or the moon blocks the sunlight completely. Then we are unable to see that one which is not getting the sunlight.
When the Moon's path carries it through earth’s umbra then it will be the total lunar eclipse. If the moon does not enter the umbra part of Earth then we have a partial lunar eclipse.
We see a total lunar eclipse when the moon is entirely within the Earth’s umbral shadow.

Hence, option C is correct.

Note: We have to remember that the Earth’s umbral part causes the lunar eclipse when Earth is in between the Sun and moon. If the Moon is in Earth’s umbra then the lunar eclipse will be total and if the moon is not in the Earth’s umbra then the lunar eclipse will be partial.
