\lim\limits_{x \to \infty } \{ {\log _{\left( {n - 1} \right)}}n.{\log _n}\left( {n + 1} \right).{\log _{\left( {n + 1} \right)}}\left( {n + 2} \right) \ldots \left\{ { \ldots {{\log }_{\left( {{n^k} - 1} \right)}}\left( {{n^k}} \right)} \right\}

, is

View answer and explanation

Correct option: C
