Task: Answer the multiple-choice question.
Query: Which compound exhibits a 10.327\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a COCc1[nH]nc2c1C1(CCSCC1)C(C#N)=C(N)O2
b CC(OC(=O)Cc1coc2cc3c(cc12)CCC3)C(=O)NCc1ccc2c(c1)OCO2
c C(=C/c1nccc2c1[nH]c1ccccc12)\c1ccccc1
d O=C(CN1CCCCC1)Nc1ccc(F)c(Cl)c1
e CC(=O)Nc1ccc(NC(=S)NC(=O)c2ccc([N+](=O)[O-])cc2)cc1
Answer: a. COCc1[nH]nc2c1C1(CCSCC1)C(C#N)=C(N)O2
