It is a complex sentence because it is an independent idea and a dependent idea in one sentence.
I like the manga's "angels of death" and "demon slayer" (you probably already know demon slayer if you like manga/anime). angels of death is a good manga, though it has a lot of blood in the anime. Also, it might get a bit boring.
It would be letter B anyone who directly works with the child like a parent basically anyone who you can truly trust
I would say figurative language since there is a simile being used when using "like" to compare the beard and hair to seaweed.
