Solution
Assertion is true but reason is false.
Explanation:
The assertion is true. This molecular evidence shows the close evolutionary relationships among organisms through similarities in DNA sequences and the universal genetic code shared by almost all organisms, indicating common ancestry.
The reason is false. Molecular evidence does not come from fossils, but rather from biochemical and genetic analyses such as DNA, RNA, and protein sequence comparisons. Fossil evidence is a separate line of evidence for evolution, based on preserved morphological structures.
