Idiom Issue:
1. "descendant from" could be a correct idiom but that doesnot mean that "descendant of" is incorrect.
2. "descendant from" could be a correct idiom but that doesnot mean that "descendant from" is superior to "descendant of".
3. "descendant from" could be a correct idiom but that doesnot mean that it is properly used in the given context.
4. "descendant from" and "descendant of" both could equally be correct and properly be used in D and E, but if E has an obvious error (i.e. wrong verb "might"), then it is less likely to be the OA than D, which doesnot have that error.

You guys might want to kill me but now I have a new querie:(
1."decendant from" is the right idiom i checked, so you guys are bang on on that.
I was reviewing the questions again and got a bit confused.
I had read somewhere,that "that" refers to immediate nouns:
One of the
substances that tell/[strike]tells[/strike]
One of the substances [strike]tells[/strike]/tell
Coming back to the original question,
the pattern of changes that have occurred So the subject here becomes changes>Plural>>Indicate..
SVA:
E. According to scientists at the University of California, the pattern of changes that have occurred in human DNA over the millennia
indicates that everyone alive today may be a descendant of a single female ancestor who lived in Africa sometime between 140,000 and 280,000 years ago.
- Subject = the pattren - singular
- Verb = indicates - singular
"That" refers to "changes" and is a plural. Therefore "That" has a plural verb "have".
The folloings are both correct:
One of the
substances that tell/[strike]tells[/strike]
One of the substances [strike]tells[/strike]/tell
