The largest binary number is:
A) 11000000
From the information given, we have that the binary includes;
11000000
01111111
00000001
10111111
In binary, the leftmost bit holds the highest value. Among the options given, this number begins with the highest significant bit (1), followed by 6 bits set to 0, making it the largest binary number.
The other numbers either have the highest bit set to 0 in the case of B, C, and D, or have fewer leading 1s compared to A, making them smaller in value in this context.
