Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 1.595\% 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=S(=O)(c1ccc(Br)cc1)N1CCCC1c1nc2ccccc2s1
(b) CSc1ccc(C(=S)N2CCCCCC2)cc1
(c) O=C(C1CCCN(Cc2ccccc2Cl)C1)N1CCCCC1.O=C(O)C(=O)O
Answer: a. O=S(=O)(c1ccc(Br)cc1)N1CCCC1c1nc2ccccc2s1
