C. Metaphor
The author is trying to say Cruel words can hurt people, the author is comparing cruel words with weapons, he is making a figure of speech, 'Cruel Words Are Weapons' is a figure of speech (Metaphor),So that makes C. Metaphor correct.
Hope this helps! :)
Not exactly sure, could you add more detail
A is the answer I’m thinking :)
B, C, and D should be capitalized. April is a proper noun because it is a name of a month. South and Northwest are directions on a compass
