Correct Answer: 1

Solution : Given: $a+b+c=1, ab+bc+ca=-1$ and $abc=-1$
$a^2+b^2+c^2= (a+b+c)^2-2(ab+bc+ca)=3$
Consider, $a+b+ c = 1$ ......(1)
⇒ $a^3 +b^3+c^3 -3abc=(a+b+c)(a^2+b^2+c^2−ab−bc−ca)$
⇒ $a^3 +b^3+c^3 =(a+b+c)(a^2+b^2+c^2−ab−bc−ca)+3abc$
⇒ $a^3 +b^3+c^3 = (1)[3-(-1)]+3\times(-1)$
⇒ $a^3 +b^3+c^3 = 4-3$
⇒ $a^3 +b^3+c^3 = 1$
Hence, the correct answer is 1.
