\lim \limits_{{x \rightarrow 0}}\left(\left(\frac{1-\cos ^{2}(3 x)}{\cos ^{3}(4 x)}\right)\left(\frac{\sin ^{3}(4 x)}{\left(\log _{e}(2 x+1)\right)^{5}}\right)\right)

is equal to

View answer and explanation

Correct option: C

Option C (18) is correct because after applying L'Hopital's rule and trigonometric limits, the expression simplifies to 18.
