Homologous organs indicate the
A
Parallel evolution
B
Natural selection
C
Convergent evolution
D
They will descend in common
Explanation: 

Detailed explanation-1: -Primarily diffusion is the basis of molecular division can be seen in some higher-level characters of structure and function that are readily observable in organisms. So, homologous organs also indicate the divergent evolution . Thus, option D is correct.

Detailed explanation-2: -Homologous organs indicates that evolution resulted in similar origins taking up different functions with time and need. The homologous structures are a result of divergent evolution.

Detailed explanation-3: -Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure below shows the hands of several different mammals. They all have the same basic pattern of bones.

Detailed explanation-4: -Homologous organs provide evidence for common ancestry that means they belong to the same origin. It provides evidence for Divergent Evolution. The organs originated from common ancestors and provide different functions called homologous organs.
