Answer:
D. to keep from using a sacred Christian term to describe historical events
Explanation:
These terms are being replaced because in this way religious diversity can be respected. Remember that "AD-BC" come from christianity:
<u>AD</u>- Anno Domini, this means "in the year of the Lord", it refers to a year after Jesus Christ was born.
<u>BC-</u> before christ.
As you can see, these terms divide universal history based on a religious event from a particular religion.
The terms "BCE-CE" don't make reference to a religious event so anyone can refer to them without any moral or ethical problem.
BCE- before common era
CE- common era
