Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -3.769\% 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: CCCc1cc(=O)[nH]c(SCC(=O)Nc2sc3c(c2C#N)CCCC3)n1
b: C[C@H](NC(=O)OCc1ccccc1)c1nnc([C@H](C)NC(=O)OCc2ccccc2)o1
c: Cc1cc(C)n2nc[n+](C)c2n1.[I-]
d: COC(=O)/C=c1/sc2nc3ccccc3n2c1=O
Answer: b. C[C@H](NC(=O)OCc1ccccc1)c1nnc([C@H](C)NC(=O)OCc2ccccc2)o1
