What is the 2’s complement of 0011 0101 1001 1100 number? A. 1100 1010 1100 1011 B. 1100 1010 0110 0011 C. 1100 1010 0110 0100 D. 1100 1010 1111 1111 E. None of the above

The 2’s complement of a binary number is formed by flipping all the bits and adding 1. So, the 2’s complement of 0011 0101 1001 1100 is 1100 1010 0110 0011.

Here is a step-by-step solution:

1. Flip all the bits of 0011 0101 1001 1100. This gives us 1100 1010 0110 0100.
2. Add 1 to the resulting number. This gives us 1100 1010 0110 0011.

Therefore, the 2’s complement of 0011 0101 1001 1100 is 1100 1010 0110 0011.

Option A is incorrect because it is not the 2’s complement of 0011 0101 1001 1100.
