1 pts
when a material is very shiny, it is said to have a high...
conductivity
ductility
luster
malleability

Explanation:

To solve Question 12, we analyze each option:

• Conductivity: Relates to heat/electricity transfer, not shininess.
• Ductility: Ability to be drawn into wires, not about shininess.
• Luster: Defined as the shininess of a material, matching the question's description of a very shiny material.
• Malleability: Ability to be hammered into sheets, not related to shininess.

So the correct option is the one with "luster".

Answer:

C. luster (assuming the option with luster is labeled as C; if the original options had labels like A - D, adjust accordingly. From the given options, the correct one is the option with "luster".)
