Orthoboric acid, `B(OH)_(3)`, is the normal end product of hydrolysis of most boron compounds. It forms flaky, white, transparaent crystals in which a planar array of `BO_(3)` units is joined by unsymmetrical `H`-bonds. In contrast to the short O-H-----O distance of 272 pm within the plane, the distance between consecutive layer in thec crystal is `318` pm, thus accounting for the pronounced basal clevage of the waxy, plate-like crystals and their low density `(1 AB g cm^(-3))`
`H_(3)BO_(3)` is slippery nature due to
A. Boric acid crystals are readily cleved along interlayer planes
B. It acts as a monobasic acid
C. The presence of banana bonds within a layer make it planar like graphite
D. The presence of hydrogen bonds between the layers
