Which of the following is NOT a common reason to terminate at lead optimization?

Explanation:
Lead optimization aims to balance potency, selectivity, pharmacokinetic properties, and manufacturability. Common reasons to stop developing a lead include very low solubility (which hampers absorption), failure to demonstrate efficacy (the compound doesn’t produce the desired effect), and an extremely difficult synthesis that cannot be scaled up for production. In contrast, extremely high solubility is not a typical reason to terminate; it generally aids absorption and formulation, making it easier to achieve the needed exposure. So the option describing extremely high solubility is the one that is not a common reason to terminate at lead optimization.
