$\log_e \left( 1 + ax^2 + a^2 + \frac{a}{x^2} \right)$ નું મૂલ્ય શું છે?

• A
  $a \left( x^2 - \frac{1}{x^2} \right) - \frac{a^2}{2} \left( x^4 - \frac{1}{x^4} \right) + \frac{a^3}{3} \left( x^6 - \frac{1}{x^6} \right) - \dots$
• B
  $a \left( x^2 + \frac{1}{x^2} \right) - \frac{a^2}{2} \left( x^4 + \frac{1}{x^4} \right) + \frac{a^3}{3} \left( x^6 + \frac{1}{x^6} \right) - \dots$
• C
  $a \left( x^2 + \frac{1}{x^2} \right) + \frac{a^2}{2} \left( x^4 + \frac{1}{x^4} \right) + \frac{a^3}{3} \left( x^6 + \frac{1}{x^6} \right) + \dots$
• D
  $a \left( x^2 - \frac{1}{x^2} \right) + \frac{a^2}{2} \left( x^4 - \frac{1}{x^4} \right) + \frac{a^3}{3} \left( x^6 - \frac{1}{x^6} \right) + \dots$
