Compare the Limits

Calculus Level 4

$\large \begin{cases} a = \displaystyle\lim_{x\rightarrow 0} \dfrac{\ln(\cos(2x))}{3x^2} \\ \\ b = \displaystyle\lim_{x\rightarrow 0} \dfrac{\sin^2(2x)}{x(1-e^x)} \\ \\ c = \displaystyle\lim_{x\rightarrow 1} \dfrac{\sqrt{x} - x }{\ln x} \end{cases}$
Then , $a , b , c$ satisfy which of the following relation :

c > b > a

b > a > c

c > a > b

a > c > b

b > c > a

a > b > c
