જો $a$ અને $b$ ધન પૂર્ણાંકો હોય કે જેથી $b > a$,તો $\lim_{n \to \infty} \left[ \frac{1}{na} + \frac{1}{na + 1} + \frac{1}{na + 2} + \dots + \frac{1}{nb} \right] = $

  • A
    $\log \left( \frac{b}{a} \right)$
  • B
    $\log \left( \frac{a}{b} \right)$
  • C
    $\log (ab)$
  • D
    $\log (a + b)$
