Solution

## The correct option is B $3\left[\mathrm{Ca}3\left(\mathrm{PO}4\right)2\right].\mathrm{Ca}\left(\mathrm{OH}\right)2$The formula for Hydroxyapatite is -Step-1Hydroxyapatite (HA) is a calcium phosphate mineral with the formula ${\mathrm{Ca}}_{10}{\left({\mathrm{PO}}_{4}\right)}_{6}{\left(\mathrm{OH}\right)}_{2}$Step-2Hydroxyapatite is a hydroxyl endomembrane of the apatite group, it is more stable compared to another calcium phosphate.Step-3Hence, its Formula is $3\left[{\mathrm{ca}}_{3}{\left({\mathrm{PO}}_{4}\right)}_{2}\right].\mathrm{Ca}{\left(\mathrm{OH}\right)}_{2}$Therefore, the formula of hydroxyapatite is explained above.
