If you mean which sentance best represents the moral of the story then it would be the second to last sentence: "At last a Wolf really did come, and the Boy cried, "Wolf! wolf!" as loud as he could: but the people were so used to hearing him call that they took no notice of his cries for help."
Just think of two things that could be compared in an unusual way! A metaphor is just a comparison that doesn't use "like" or "as". For example, a simile would be "My love is like a rose" but a metaphor would be "My love is a rose" If you think of it this way, it might be easiest to think of a simile then take away "like" or "as". Be creative with it and have fun
B. Conspicuously in this context means attracting attention.
