Answer»

`LiCl, AlH_(3) and SiH_(4)`
`LiCl, AlCl_(3) and SiH_(4)`
`LiH, AlCl_(3) and SiCl_(2)`
`LiH, AlH_(3) and SiH_(2)`

Solution :On heating with excess of air `Li, NA and K` forms following OXIDES
`4Li+O_(2)rarr underset("Lithium monoxide")(2Li_(2)O)`
`2Na+O_(2)overset(575K)rarr underset("SODIUM peroxide")(Na_(2)O_(2))`
