Answer:
b) hammered into shape
Explanation:
According to the excerpt from Stuff Matters by Mark Miodownik, it is narrated that metals were a great discovery which replaced the use of stones and bones as they were easily malleable unlike the other previously used material.
The line from the excerpt that provides context that supports the meaning of the word malleable is "hammered into shape". This is because for a thing to be malleable, it means that it its shape can be easily altered.
