Answer:
The sentence that uses the word malleable correctly is;

An example of a malleable metal is gold, which can be hammered into a gold leaf
Malleability in metals is due to their ability to have their nuclear shifted while maintaining their bonds due to the ability for electrons to move freely such that they are replaced with ease
Therefore, the sentence that uses the word malleable correctly is the gold wedding band was malleable such that it was able to be shaped into a beautiful ring.
