Given $K_1=1110$ and $K_2=0101,$ encrypt the message

$Y=11011001$

using the two round Feistel cipher defined by

$K_i=x_1{x}_2{x}_3{x}_4,$

$f_{K_i}(b_1{b}_2{b}_3{b}_4)=(x_{1}o+b_{1}o+b_3,x_{2}o+b_{2}o+b_3,x_{3}o+b_{1}o+b_3,x_{4}o+b_4),$

NOTE: Choose the MOST correct alternative.

a$.00011000$

b$.10000100$

c$.00111000$

d$.01101000$

e$.01001000$

f$.10000110$

g$.10000001$

h$.10000011$
