When a substance A reacts with water it produces a combustible gas B and a solution of substance C in water. When another substance D reacts with this solution of C, it also produces the same gas B on warming but D can produce gas B on reaction with dilute sulphuric acid at room temperature. A imparts a deep golden yellow colour a smokeless flame to Bunsen burner. A,B,C, and D respectively are `:`

`K,H_(2),KOH,Al`

`Na,H_(2),NaOH,Zn`

`CaC_(2),C_(2)H_(2),Ca(OH)_(2),Fe`

`Ca,H_(2),Ca(OH)_(2),Sn`
