Appositive phrases are used to further describe the nouns before them. They act like adjectives, although they aren't necessarily always adjectives. In most cases, they are separated from the rest of the sentence using commas on both sides. So yes, you are right - the appositive phrase in this sentence is either tulip or daffodil.
The subgenre of the given poem is BALLAD.
Danny Reever is a poem by Rudyard Kipling. In 1890, it was one of the first of the Barrack-Room ballads. It is about a British soldier who is being executed in India. The execution was in full view of his regiment. The poem is composed of the remarks made by the spectators as they watch the soldier being hanged.
Hello! Gramatically, let's look at each choice-
(a) says: Mrs. Anderson flies to Sweden tomorrow her plane leaves at 2:00 P.M.
This can't be right, because it's a run-on sentence! If someone were to say this outloud, it would sound as if someone wasn't "taking their time"!
(b) says: Mrs. Anderson flies to Sweden tomorrow, her plane leaves at 2:00 P.M.
This one looks correct. It has a comma which adds a pause. It also connects both statements made in the sentence.
(c) says: Mrs. Anderson flies to sweden tomorrow, and her plane leaves at 2:00 P.M.
This one wouldn't be correct because its listing ideas with "and" in between. It's as if the speaker is saying "she does this and this and that and that..."
So your best choice would be B.
