Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 16.704\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=S1(=O)C[C@@H](O)[C@@H](Nc2ccccc2)C1
b) O=C(O)c1ccc(NC(=O)c2cn(-c3ccccc3)nc2-c2ccc(F)cc2)cc1
Answer: a. O=S1(=O)C[C@@H](O)[C@@H](Nc2ccccc2)C1
