b) Behaved as a black hole during its transit.
c) Is black in colour.
d) Obstructed all light from the Sun.
Answer »Answer: (b)
The black color on the sun is because the planet behaved as a black hole during its transit. A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and Earth (or another planet), becoming visible against (and hence obscuring a small portion of) the solar disk.
During a transit, Venus can be seen from Earth as a small black disk moving across the face of the Sun. The duration of such transits is usually measured in hours (the transit of 2012 lasted 6 hours and 40 minutes).
