Neg replaces the value of operand with its two's
compliment
In simple words, we are performing not and
add 1 on the given operand.
Let's see a step-by-step explanation.
NEG 1 0010 1110
1. First we will find the 1's compliment of the operand. We will
replace 1 by 0 and 0 by 1.
So 1 0010 1110 becomes 0 1101 0001
2. Now we will add 1 to the result.
-------------------------------
Thus, NEG 1 0010 1110 will give us 0 1101 0010 which is
option C
Now let's take a look at other options. Only option
B is somewhat resembling to option C. It
is interesting to not that option B is 1's
compliment of the operand. We are adding 1 while performing Negate
i.e. NEG. So our answer will be option
C.
