The correct answer is: A) Vanity is dangerous.
This Greek myth tells the story of Narcissus, known for his incredible beauty, and Echo, a nymph who fell in love with him. 
Narcissus was supposed to have a long life, but only if he never saw himself. When he rejected Echo, he angered the Gods and happened to fall in love with himself after seeing his own reflection in the water. The extreme vanity of Narcissus ultimately led to his death.

Hello. You did not show line 4 to which the question refers, which makes it impossible for the question to be answered accurately, but I will try to help you in the best possible way.
The definition "Showing great intelligence" will be the correct one if line 4 presents a text referring to smartness, academic quality and wisdom.
The definition "Full of light" is correct if line 4 has a text on clarity, lighting and brightness.
The definition "Excellent or superior in performance" will be correct if line 4 presents a text about something or someone who has a great capacity to complete activities in an amazing way.
