Task: Answer the multiple choice question.
Question: Which compound exhibits a 19.605\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) O=[N+]([O-])c1ccc(N/N=C/c2cn(-c3ccccc3)nc2-c2ccccc2)cc1
b.) O=c1cc(O)nc(-c2ccccc2)s1
c.) COc1ccc([C@@H](C)NC(=O)c2ccc3oc(C(C)C)nc3c2)cc1
Answer: b. O=c1cc(O)nc(-c2ccccc2)s1
