The correct options are
A Na+H2O (cold)
D Ca+H2O (hot)
Sodium and calcium being highly reactive metals, react with cold water, other than hot water and steam, and liberate H2 gas (which catches fire).
Again, Iron being a low reactive metal reacts only with steam to liberate hydrogen gas. It does not react with cold water.
Mg, though is a reactive metal, reacts only with warm water and steam and does not liberate H2 on reacting with cold water.
