Multiple Choice

After reading the paragraph, answer the question(s) that follow(s) .
Generally, we think of viruses as nasty little bits of business that arrive unwanted, take over our cellular functions, and then move along to their next victim. Recently, however, it was discovered that the human genome actually contains about half a million 'viral fossils.' Indeed, about 8% of human DNA appears to originate from viral DNA that became permanently incorporated into the human genome. And furthermore, in some cases, identical viral fossils have been found in the chimpanzee genome. These incredible findings suggest that we might need to take a broader view of how viruses and people truly interact and have done over the millennia.
-These observations also suggest that

A) humans and viruses have been coevolving in a relatively stable way for much of the history our species.
B) humans and chimpanzees have been separately infected by the same virus at different times in their evolutionary past.
C) viral DNA is unable to access egg or sperm cells; rather, viruses can only attack nongerm cells.
D) viruses are actually relative new phenomena that likely did not exist in the earliest stages of human evolution.
