Answer:
The ability to "shine" is known as lustre. Metals display lustrous properties than non metals.
- Sulphur is a non metal.
- Boron is also a non metal.
- Calcium is a metal
- Carbon is a non metal.
Hence Calcium will exhibit lustrous properties than other elements. That is, calcium is likely to be shiny.

The Correct Solution is Calcium.
- Calcium is metal whereas Sulfur, Boron and Carbon are non-metals.
- Metallic lustre is a pretty common feature of metals. The manner light interacts with the surface of a crystal or mineral is called lustre.
- The free electrons in metals are responsible for their shiny appearance.
- Metals have low ionisation energies, and when they undergo chemical reactions, they often lose electrons (i.e. get oxidised).
- Normally, they don't receive electrons.
- Shiny metals are excellent conductors of electricity.
- A good example of an intensive property is lustre.
- The term "lustre" refers to a categorization of optical attributes.
- Metals are solids at room temperature. Exception: Mercury which is liquid at room temperature.
- Metals are malleable and ductile.
- The melting and boiling points of metals are extremely high.
- With the exception of sodium and potassium, which are soft and can be cut with a knife, all metals are hard.
