What can be said about the presence of water on Venus?
A)The Venera lander first sampled the atmosphere and found abundant water vapor there.
B)Mariner 2 monitored the 1.35-cm line, which is absorbed by water. Little 1.35-cm radiation was absorbed, thus suggesting little or no water.
C)Mariner 2 monitored the 1.35-cm line, which is absorbed by water. Little 1.35-cm radiation was detected, suggesting it was absorbed by water vapor in the atmosphere.
D)Radio waves from Earth, bounced off of Venus, were used to measure the rotation rate of Venus. The same radio wave detector observed the radio waves associated with water, thus suggesting abundant water on Venus.
