यदि $x = a \sin \theta - b \cos \theta$ और $y = a \cos \theta + b \sin \theta$ है,तो निम्नलिखित में से कौन सा सत्य है?

  • A
    $x^{2} + y^{2} = a^{2} - b^{2}$
  • B
    $x^{2} + y^{2} = a^{2} + b^{2}$
  • C
    $\frac{x^{2}}{a^{2}} + \frac{y^{2}}{b^{2}} = 1$
  • D
    $\frac{x^{2}}{y^{2}} + \frac{a^{2}}{b^{2}} = 1$
