જો શૂન્યતર $x$ માટે,$af(x) + bf\left( {\frac{1}{x}} \right) = \frac{1}{x} - 5,$ જ્યાં $a \ne b,$ હોય,તો $\int_1^2 {f(x)\,dx = } $

  • A
    $\frac{1}{{({a^2} + {b^2})}}\left[ {a\log 2 - 5a + \frac{7}{2}b} \right]$
  • B
    $\frac{1}{{({a^2} - {b^2})}}\left[ {a\log 2 - 5a + \frac{7}{2}b} \right]$
  • C
    $\frac{1}{{({a^2} - {b^2})}}\left[ {a\log 2 - 5a - \frac{7}{2}b} \right]$
  • D
    $\frac{1}{{({a^2} + {b^2})}}\left[ {a\log 2 - 5a - \frac{7}{2}b} \right]$
