Solution

The correct options are
A high oxidation potential
C good conductor of heat and electricity
D solubility in liquid ammonia
A) Alkali metals are good electrical and thermal conductors due to presence of valence electrons, which can move freely across the crystal lattice.
B) Alkali metals are also very good reducing agents. They have high oxidation potential and can easily donate electrons.
C) The melting and boiling points of alkali metals are very low due to weak bonding in the crystal lattice.
D) They have good solubility in liquid ammonia. Their solution in ammonia is blue in colour.
