Sorry I haven't tested all the options yet :P

Yes
taking 010 for X and 01 for Y will leave with one option i.e. C
0
Please explain the process properly

as you know that when x2 will be 1 then in all 16 cases you will get x>y so make only for x1x0y1y0(for 4 varibale) and add x2 in each max term you will get your answer.
0
Take
X2>0
X1>1
X0>0
Y1>0
y0>1
Option A. fails at second condition
Option B fails at third condition
Option D fails at second condition
Option C gives 1 to all the conditions

MadeEasy Test Series: Digital Logic  Number Representation
two 2's complement nos. having sign bits x and y are added and the sign bit of result is z. Then the occurrence of overflow is indicated by the expression??? The answer is given as x'y'z + xyz' . As far as I know, Overflow is indicated by Cn XOR C(n1). So, here Cn is 'z' and C(n1) is x+y . Whose XORing gives me.. x'y'z + xz' + yz'.
