Answer:

I think is B

Explanation:

Because maybe 1,0001 = 11 because the 1 at the front and 1 at the end are the same. Because if 1,000 10 = 10 equals 10 it seems wrong ehh because 10 at the end, it seems impossible and here are C and D, 1,100 = 10 and 1011 = 8 there seems to be no connection between the two ... so my real answer is 1,000 1 = 11 ...

I hope that only helps because I know the answer, because I've studied it because that's ehhh ... just brainliests and follow
