Answer 2

Correct option is
D
0
ab+bc+ca=0
bc=−ca−ab
bc=−a(b+c)---eq1
like wise,
ab=−c(a+b)---eq2
& ca=−b(c+a)---eq3
=
a
2
−bc
1
​
+
b
2
−ca
1
​
+
c
2
−ab
1
​


taking the value from eq1, 2&3
=
a
2
+a(b+c)
1
​
+
b
2
+b(a+c)
1
​
+
c
2
+c(a+b)
1
​

=
a(a+b+c)
1
​
+
b(a+b+c)
1
​
+
c(a+b+c)
1
​

=
abc(a+b+c)
ab+bc+ca
​


As ab+bc+ca=0
So, =0
