Answer :
The correct answer is C. It means we can see only 11.6% of the lit portion of the Moon. An 11.6% illuminated Moon means that from Earth we can only see 11.6% of the Moon's surface that is lit by the Sun, which corresponds to a particular phase in its orbit.
When we say that the Moon is 11.6% illuminated, it means that we can see only 11.6% of the Moon's surface that is lit by the Sun from our perspective on Earth. At any given time, half of the Moon is illuminated by the Sun due to its spherical shape, but only a portion of that illuminated half is visible to us, which varies as the Moon goes through its phases. The opposite side, which receives no direct sunlight, is not visible and is in shadow. The correct answer is C. It means we can see only 11.6% of the lit portion of the Moon.
