Solution
The correct option is
C
{
0
,
1
,
3
}
Given
U
=
{
x
|
x
5
−
6
x
4
+
11
x
3
−
6
x
2
=
0
}
x
5
−
6
x
4
+
11
x
3
−
6
x
2
=
0
x
2
(
x
3
−
6
x
2
+
11
x
−
6
)
=
0
x
2
(
x
2
−
5
x
+
6
)
(
x
−
1
)
=
0
x
2
(
x
−
3
)
(
x
−
2
)
(
x
−
1
)
=
0
Hence
U
=
{
0
,
1
,
2
,
3
}
A
=
{
x
|
x
2
−
5
x
+
6
=
0
}
x
2
−
5
x
+
6
=
0
(
x
−
3
)
(
x
−
2
)
=
0
Hence
A
=
{
2
,
3
}
B
=
{
x
|
x
2
−
3
x
+
2
=
0
}
x
2
−
3
x
+
2
=
0
(
x
−
2
)
(
x
−
1
)
=
0
B
=
{
1
,
2
}
A
∩
B
=
{

}
(
A
∩
