Answer
Correct option: C.
It hydrolyses to give an acidic solution
c
$N{a_2}{B_4}{O_7}.10{H_2}O\,\,\overset{HOH}{\rightarrow}\,\mathop {NaOH\,}\limits_{SB} + \,\mathop {{H_3}B{O_3}}\limits_{WA} $
$N{a_2}{B_4}{O_7}.10{H_2}O\,\,\overset{HOH}{\rightarrow}\,\mathop {NaOH\,}\limits_{SB} + \,\mathop {{H_3}B{O_3}}\limits_{WA} $
