Shivam Dave from JAMNABAI NARSEE SCHOOL, Gandhinagar

The answer is C. As it was a lunar eclipse, in which the Earth comes between the Sun and the Moon. The answer won't be A as there is no bird flying in the space. The answer won't be B as there couldn't be dust clouds blocking the sun. The won't be D as a satellite is not that much big to block Moon's Rays.
