The selection of silver, copper, tin, and zinc as commonly found metals in dental alloys makes sense because these metals are specifically chosen for their desirable properties in restorative dentistry. Silver is often used for its strength and aesthetic qualities, while copper contributes to the hardness and corrosion resistance of the alloy. Tin aids in achieving better flow properties when the alloy is mixed, thus improving adaptation to tooth structures during restorations. Zinc is included for its ability to prevent oxidation and improve the overall longevity of dental materials.

In contrast, the other options include metals that are either less common in dental alloys or are not used due to their properties. For instance, while gold, palladium, and platinum are precious metals used in dental applications (primarily for high-quality restorations), the specific combination listed in the first option is more frequently encountered in contemporary dental practices. Aluminum and mercury, although used in some specific contexts, do not represent the standard for dental alloys. Likewise, lead and iron are not suitable due to their toxicity and potential for corrosion in the mouth.
