Answer 2

$</p><p>\huge\blue{\boxed{Explanation:}}$

$que.. {2}^{n - 1} \times {5}^{n - 4} = {5}^{9}$

$= > \frac{ {2}^{n} }{2} \times \frac{ {5}^{n} }{ {5}^{4} } = {5}^{9}$

$= > {2}^{n - 1} \times {5}^{n - 1} = {5}^{12}$

$= > {10}^{n - 1} = {5}^{12} \\ which \: can \: not \: be \: possible$

hence, its A contradiction!!
