As we learnt in 

Occurence of Boron -

Does not occur free in nature and its chief minerals are

Borax (or Tincal) - Na_{2}B_{4}O_{7}\cdot 10H_{2}O

Boric Acid  H_{3}BO_{3}

Kernite - Na_{2}B_{4}O_{7}\cdot 2H_{2}O

Colemanite - Ca_{2}B_{6}O_{11}\cdot 5H_{2}O

Boracite - 2Mg_{3}B_{8}O_{15}\cdot MgCl_{2}

-

 

 Each oxygen atom has 2 lone pairs and 2 bond pair making it sp3 hybridized.

B has 3 bond pairs making it sp2 hybridized.


Option 1)

sp^{2}\; \; and\; \; sp^{2}

Option 3)

sp^{3}\; \; and\; \; sp^{2}

This option is incorrect.
