Task: Answer the multiple-choice question.
Question: Which compound has a 2.575\% 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(Nc1ccc(F)cc1)c1ccc(S(=O)(=O)NCc2cccnc2)cc1
b: COc1cccc(/C=C2\NC(=O)NC2=O)c1O
c: C=CCc1ccc(OCCOCCOc2ccc(C)cc2[N+](=O)[O-])c(OC)c1
d: Cc1cc2c(cc1S(=O)(=O)NCc1ccccc1)NC(=O)CO2
e: O=C(NCCCn1ccnc1)/C(=C\c1ccc(Br)cc1)NC(=O)c1ccccc1F
Answer: c. C=CCc1ccc(OCCOCCOc2ccc(C)cc2[N+](=O)[O-])c(OC)c1
