How does Diotima/Socrates assess the value of biological children as opposed to ideas (or children of the soul)?

a) They consider biological children to be more valuable because they are tangible and contribute to the continuation of the human race.
b) They believe that ideas, or children of the soul, are more valuable because they represent eternal truths and contribute to intellectual and spiritual growth.
c) They view both biological children and ideas as equally valuable, each serving different purposes in human life and society.
d) They argue that biological children are valuable in the material realm, while ideas, or children of the soul, are valuable in the realm of the intellect and spirit.
