Which of the following properties describes the diagonal relationship between boron and silicon?
\( \mathrm{P} \)
(a) \( \mathrm{BCl}_{3} \) is not hydrolysed while \( \mathrm{SiCl}_{4} \) can be hydrolysed
(b) Both form oxides \( \mathrm{B}_{2} \mathrm{O}_{3} \) is amphoteric and \( \mathrm{SiO}_{2} \) is acidic
W
(c) Both metals dissolve in cold and dilute nitric acid
(d) Silicide and boride salts are hydrolysed by water
