यदि $\int_{0}^{100 \pi} \frac{\sin ^{2} x}{e^{\left(\frac{x}{\pi}-\left[\frac{x}{\pi}\right]\right)}} d x=\frac{\alpha \pi^{3}}{1+4 \pi^{2}}, \alpha \in R$,जहाँ $[x]$ वह महत्तम पूर्णांक है जो $x$ से छोटा या उसके बराबर है,तो $\alpha$ का मान है:

  • A
    $100(1-e)$
  • B
    $200(1-e^{-1})$
  • C
    $150(e^{-1}-1)$
  • D
    $50(e-1)$
