Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 2.331\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) Cc1cn(C2CC(OC(=O)C(C)C)C(CO)O2)c(=O)[nH]c1=O
(b) O=C(NCc1cccnc1)C1CCC(c2ccc(Cl)cc2)CC1
(c) Cc1nn(C(=O)c2ccco2)c(C)c1Br
(d) O=C(CNS(=O)(=O)c1ccc(Br)s1)N1CCN(C(=O)c2ccco2)CC1
Answer: a. Cc1cn(C2CC(OC(=O)C(C)C)C(CO)O2)c(=O)[nH]c1=O
