Identify the example of zero-dimensional $(0D)$ nanostructure from the following.

Which of the following is not correct?

Sodium stearate forms in water:

In which of the following is the Tyndall effect not observed?

In an electrophoresis setup,a colloidal solution of glycine having a $pH$ of $5.97$ is kept at constant $T$ and $P$. What will happen if a few drops of base are added to it?

The correct statement$(s)$ related to colloids is(are):
$(A)$ The process of precipitating colloidal sol by an electrolyte is called peptization.
$(B)$ Colloidal solution freezes at a higher temperature than the true solution at the same concentration.
$(C)$ Surfactants form micelles above the critical micelle concentration $(CMC)$. $CMC$ depends on temperature.
$(D)$ Micelles are macromolecular colloids.
