Solution

The correct options are
A
Strength

B
Lustre

C
Electrical and Heat Conduction

The metallic bond is the cause for many of the properties of metals, such as strength, malleability, ductility, lustre, conduction of heat and electricity.
Because the electrons move freely, metals have some electrical conductivity. Metals also conduct heat since the free electrons can transfer the energy at a faster rate.
The free electrons present in metal atoms absorb energy from light and release back to produce the phenomenon of reflection, thus explaining the property of lustre.
