यदि $l, m$ $(l < m)$ समीकरण $ax^2 + bx + c = 0$ के मूल हैं,तो $\lim_{x \rightarrow \alpha} \frac{|ax^2 + bx + c|}{ax^2 + bx + c} = $

  • A
    $\frac{|a|}{a}, \forall \alpha \in R$
  • B
    $\frac{-|a|}{a}$,जब $\alpha \notin (l, m)$
  • C
    $\frac{-|a|}{a}$,जब $\alpha \in (l, m)$
  • D
    $\frac{|a|}{a}, \alpha \in (l, m)$
