  • A
    $0$
  • B
    $1$
  • C
    Does not exist
  • ✓
    None of these

Answer

Correct option: D.
None of these
d
(d) $\mathop {{\rm{lim}}}\limits_{x \to 0} \frac{{{e^{1/x}}}}{{{e^{\left( {\frac{1}{x} + 1} \right)}}}} = \mathop {{\rm{lim}}}\limits_{x \to 0} \frac{{{e^{1/x}}}}{{{e^{\frac{1}{x}}}.e}}$

$ = \mathop {{\rm{lim}}}\limits_{x \to 0} \frac{1}{e} = {e^{ - 1}}$.
