Answer

A

Explanation

(i) `underset((P))(B_(2)O_(3))+3C+3Cl_(2) to underset((Q))(2BCl_(3))+3CO uarr`
(ii) `underset((Q))(BC l_(3))+3H_(2)O to underset((R))(H_(3)BO_(3))+3HCl`
(iii) `BN+3H_(2)O to underset((R))(H_(3)BO_(3))+3HCl`
(iv) `underset((Q))(4BC l_(3))+3LiAlH_(4) to underset((S))(2B_(2)H_(6))+3LiCl+3AlCl_(3)`
(v ) `underset((S))(B_2H_(6)+6H_(2) O )to underset((R))(2H_(3)BO_(3))+6H_(3) uarr`
(vi ) ` underset((S))(B_(2) H_(6))+2NaH ) to underset((T))(2NaBH_(4))`
