The answer to the first one would be C. Onomatopoeia. Just for future reference, the definition of Onomatopoeia is the process of creating a word that imitates, resembles, or suggests the sound that it is describing. Here, the bridge made a 'boom' sound, so it is imitating/telling us the sound the bridge made.
