જો $a, b, c$ બધા અલગ હોય અને $\left| \begin{array}{ccc} a & a^3 & a^4 - 1 \\ b & b^3 & b^4 - 1 \\ c & c^3 & c^4 - 1 \end{array} \right| = 0$ હોય,તો:

  • A
    $abc(ab + bc + ca) = a + b + c$
  • B
    $(a + b + c)(ab + bc + ca) = abc$
  • C
    $abc(a + b + c) = ab + bc + ca$
  • D
    આમાંથી કોઈ નહીં
