b. 2
c. 3
d. 4
ANSWER: 4
NASA’s Pluto Exploration Programme has found the dwarf planet is geologically active even after 4 billion years indicating this planet could be alive. The first colour images of Pluto have revealed a blue haze and small exposed regions of water ice on Pluto. Patterns of water ice have uneven distribution and the blue sky on Pluto results from scattering of sunlight by soot like particles referred to as tholins. However, scientists have said it is not possible for Pluto to have life once because it is -400 degree F and too cold for life. Pluto is currently the only object in the Kuiper Belt with multiple moons.
