D. 3,009,760,012

Answer 1

A. 3,976,012 is the answer

Answer 2

: B is the answer!

:
The problem says nothing about millions, so that whole section is left as 0.
Next, you look at the thousands (976 thousands) which are placed directly in front of the hundreds, tens and ones (just a 12 there.)

The answer is 3,000,976,012 :)
