Stephenie Meyer has stated that the apple on the cover represents the forbidden fruit from the book of Genesis. It symbolizes Bella and Edward's love, which is forbidden, similar to the fruit of the Tree Of knowledge, as is implied by the quote from Genesis 2:17 that is quoted at the beginning of the book. It also represents Bella's knowledge of what good and evil are, and the choice that she has in partaking of the "forbidden fruit", Edward, or choosing not to see him.
The Twilight apple cover was designed by Gail Doobinin.

because of temptation==goes back to when eve offered an apple to Adam and he took into temptation
Edward catches the apple on page 18 of "Twilight."
It could be Twilight, although that is just two hands holding an apple and it is not bitten.
Yes, the cover of Twilight featuring an apple and hands is appropriate in the context of the storyline, as it symbolizes themes of temptation and forbidden love that are central to the book.
