<span> Both are similar in size, mass, density,
and volume. However, during the last few years scientists have found
that the kinship ends here. Venus is very different from Earth. It has
no oceans and is surrounded by a heavy atmosphere composed mainly of
carbon dioxide with virtually no water vapor. Its clouds are
composed of sulfuric acid droplets. At the surface, the atmospheric
pressure is 92 times that of the Earth's at sea-level.</span><span>

Answer:
The correct answer is B. the two strands of DNA must separate.
Explanation:
DNA is a double-stranded structure. The two strands are joined together by the formation of hydrogen bonds between complementary nucleotides. So before the replication takes place these two strands must be separated.
The separation of DNA strand is accomplished by the action of a helicase enzyme which breaks the hydrogen bond between complementary nucleotides and separated the two DNA strands.
After separation, the DNA polymerase binds to separated DNA and replicating the DNA. So the right answer is B.
