यदि $y = 2x^2 - 1$ है,तो $\left[ \frac{1}{y} + \frac{1}{3y^3} + \frac{1}{5y^5} + \dots \right]$ का मान क्या होगा?

  • A
    $\frac{1}{2} \left[ \frac{1}{x^2} - \frac{1}{2x^4} + \frac{1}{3x^6} - \dots \right]$
  • B
    $\frac{1}{2} \left[ \frac{1}{x^2} + \frac{1}{2x^4} + \frac{1}{3x^6} + \dots \right]$
  • C
    $\frac{1}{2} \left[ \frac{1}{x^2} + \frac{1}{3x^6} + \frac{1}{5x^{10}} + \dots \right]$
  • D
    $\frac{1}{2} \left[ \frac{1}{x^2} - \frac{1}{3x^6} + \frac{1}{5x^{10}} - \dots \right]$
