Answer:
Option C
Step-by-step explanation:
It's not option A because a metaphor is comparing two things without using the words like or as. It's not option B because a simile is comparing two things using the words like or as. It's not an idiom because it is a word, or a phrase not meant to be taken literally but to provide a different meaning. Your answer is option C or "personification." Personification is giving human qualities to inhuman objects, in this case "The steel drums sang to me," is giving human qualities to an inhuman object because drums cannot sing like humans.
Hope this helps.
