As we have learnt,

 

Action of boranes with water -

Readily hydrolysed by water to give boric acid

- wherein

B_{2}H_{6}+6H_{2}O\rightarrow 2H_{3}BO_{3}+6H_{2}

 

 Hydrolysis of diborane:
 

B_{2}H_{6}+6H_{2}O\rightarrow 2H_{3}BO_{3}+6H_{2}\uparrow

Boric acid accepts a lone pair of electron from OH- ion, thereby acts as monobasic Lewis acid.

H_3BO_3 + H_2 O\rightarrow H_4BO_4^{\ominus} + H_3O^{+}

Therefore, option (1) is correct.
