Task: Answer the multiple choice question.
Question: Which compound exhibits a 3.608\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COCCN(Cc1nc2ccccc2c(=O)[nH]1)C(=O)c1cccc(S(=O)(=O)N2CCCC2)c1
b: CCOC(=O)CSC1=C(C#N)C(c2ccccc2C)C2=C(CCCC2=O)N1
c: COc1ccc(N2CCCn3c2nc2c3c(=O)n(Cc3ccccc3)c(=O)n2C)c(OC)c1
d: O=C(CNc1cccc(S(=O)(=O)N2CCCC2)c1)Nc1cccc(Br)c1
Answer: a. COCCN(Cc1nc2ccccc2c(=O)[nH]1)C(=O)c1cccc(S(=O)(=O)N2CCCC2)c1
