Final answer:
The serpent tempted Adam and Eve with the promise of becoming like Gods upon eating from the Tree of Knowledge, which is consistent with the biblical narrative where God recognizes the change in their knowledge. The correct answer is option: a. Gods.
Step-by-step explanation:
The serpent tempted Adam and Eve by telling them they would be like Gods. In the biblical account of Genesis 3, the serpent convinces Eve by stating that eating from the Tree of Knowledge of Good and Evil would open their eyes, and they would be like God, knowing good and evil.
Following this event, it is said in Genesis that God acknowledged that 'The man has now become like one of us, knowing good and evil.' This indicates that the serpent's temptation involved becoming more like the divine beings by gaining knowledge that was previously reserved for God alone.
