Problem statement: Answer the multiple choice question.
Question: Which compound has a -2.151\% human ether-à-go-go related gene (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: O=C(CSc1ccc(Cl)cc1)N/N=C/c1cccnc1
b: Cc1ccsc1-c1nc(CSCC(=O)N2CCC3(CC2)OCCO3)c(C)o1
c: CCOC(=O)CN1N=C(/C=C/c2ccccc2)CCC1=O
d: O=C(COC(=O)c1cc([N+](=O)[O-])ccc1NCCO)Nc1cccc(S(=O)(=O)N2CCCC2)c1
e: COC(=O)c1ccc(NC(=O)c2ccco2)cc1
Answer: a. O=C(CSc1ccc(Cl)cc1)N/N=C/c1cccnc1
