In the garden of Eden, God provided everything for man because of His divine attribute of:

mercy

righteousness

justice

love

The answer is (D) - Love.

In the first "Book" of the bible Genesis, it says that God created everything, and that there was no sin. Tho that sounds like righteousness, most believers in Christ will tell you its love. So according to the Bible, god gave everything to man because he loved them. Then also according to the Bible "man" ate the apple on the tree in which the Bible said not to, telling "man" they had sinned giving them the knowledge of "Good and Evil".
