Which is more stable among `alpha-D-` glucose and `beta-D-` glucose? Why?

Explanation

`beta -D-` glucose is more stable. In `alpha-D` glucose -OH group at C-1 is in axial position while in `beta`-D- glucose, -OH group at C-1 is equatorial.
Group at other carbon atoms of `alpha-D-` glucose and `beta-D-` glucose in equatorial position.
