MLE here implies Maximum likelihood estimator.
Statements are :
$1$. MLEs are always consistent
$2$. MLEs are always unbiased
$ 3$. MLEs follow normal distribution asymptotically
$4$. MLEs need not be a unique estimator
$1st$ is true and $2nd$ is false I know it I want to know reasoning behind $3$ and $4$ statement please give any example if you can.
