Task: Answer the multiple choice question.
Query: Which compound has a 4.395\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCC(C)NC(=O)c1ccc(NC(=O)C2=C(C)OCCS2)cc1
b: Cc1c(Cc2ccccc2)c(NCCN(C)C)n2c(nc3ccccc32)c1C#N
c: COc1ccc(C)cc1NC(=O)C1CCCCC1C(=O)O
d: O=c1[nH]c(=O)n(C2CCCCC2)c(O)c1/C=C/C=Nc1ccccc1
e: O=C(CCCCn1c(=O)[nH]c2ccsc2c1=O)NCC1CCCO1
Answer: b. Cc1c(Cc2ccccc2)c(NCCN(C)C)n2c(nc3ccccc32)c1C#N
