Option 4: $a\neq b\neq c$
Correct Answer: $a=b=c$
Solution : Given: $a^{2}+b^{2}+c^{2}-ab-bc-ca=0$ Multiplying the whole equation by 2, $2a^{2}+2b^{2}+2c^{2}-2ab-2bc-2ca=0$ ⇒ $(a-b)^2+(b-c)^2+(c-a)^2=0$ ⇒ $(a-b)^2=(b-c)^2=(c-a)^2=0$ [If the sum of squares of three numbers is zero, then each number will also be zero] ⇒ $a=b=c$ Hence, the correct answer is $a=b=c$.
