Why or what caused the Indus Valley civilization to disappear?

A. flooding
B. drought
C. foreign invaders
D. no known cause

I know it isn't B because they built mounds to block the flooding. It could be B, C, or D. I am leaning towards C. Can you guys help me?

I agree with you about C.
Ok thanks!
You're welcome.
I took the test and it said no known cause! :(
I got it wrong and so now I got 2/3 on my quiz!
Is this a Connexus course you're taking? I can't remember how many errors I've seen in their answer choices, in their terminology, and in their texts and tests.

If you can get into a better school, you'll get a better education.
