Task: Answer the multiple choice question.
Question: Which compound has a 10.462\% 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: CCOc1cc(C(=O)NCCN2C(=O)S/C(=C\c3cccnc3)C2=O)cc(OCC)c1OCC
b: COCCn1c(=NC(=O)CCS(=O)(=O)c2ccccc2)sc2cc(C)ccc21
c: COc1cccc(CNC(=O)CCCNS(=O)(=O)c2cccs2)c1
d: S=c1sc2ncccc2n1-c1ccccn1
e: Cc1cc(C(=O)Nc2sc3c(c2C#N)CCC(C(C)(C)C)C3)no1
Answer: d. S=c1sc2ncccc2n1-c1ccccn1
