"the trouble is," sighed the doctor, grasping her meaning intuitively, "that youth is given up to illusions. it seems to be a provision of nature; a decoy to secure mothers for the race. and nature takes no account of moral consequences, of arbitrary conditions which we create, and which we feel obliged to maintain at any cost."

-nature forces women into motherhood.

-young people are prone to having delusions.

-morals play no role when we choose who we love.

In the given excerpt, the larger idea is that is being implied or referred to by the doctor is that 'impulses often overrule an individual's moral senses'. By nature, he implies the universal idea through which everyone can associate(broader idea) 'instincts or illusions created by us' that drive an individual to neglect the moral consequences by which the author implies 'sense of morality, virtue, ethics, and integrity'.

The idea that is being referred to(in simple terms) is that humans often gets overpowered by their self-created 'illusions or fancies' that they tend to suppress the virtue of recognizing the difference between good and bad(being morally right). Thus, option A is the correct answer.
