Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 6.026\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(O)c1cc(-c2ccc3ccccc3n2)nc2ccccc12
(b) Cn1cc(S(=O)(=O)N2CCc3ccccc32)cc1C(=O)Nc1ccc(Cl)cc1
(c) Nc1nnc(SCCCC(=O)c2ccc(Br)cc2)s1
Answer: a. O=C(O)c1cc(-c2ccc3ccccc3n2)nc2ccccc12
