I. The interconversion between the $\alpha$ - and $\beta$-pyranose forms of D-glucose is indeed acid-catalyzed, as the reaction involves the opening of the pyranose ring followed by reclosure, which can be facilitated by acid.III. Both anomers ($\alpha$ and $\beta$) are optically active because they are stereoisomers that differ in the configuration around the anomeric carbon, thus rotating plane-polarized light differently.
