Task: Answer the multiple-choice question.
Question: Which drug exhibits a 13.391\% 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=C(Nc1ccc(Br)cc1)C1CC(O)CN1C(=O)Oc1ccccc1
(b) Cc1ccc(C)c(/C=C(\C(=O)O)c2ccc(S(=O)(=O)N3CCCCC3)s2)c1
(c) CSc1ccc(CN2CCCC(CO)(Cc3ccccc3)C2)cc1
Answer: a. O=C(Nc1ccc(Br)cc1)C1CC(O)CN1C(=O)Oc1ccccc1
