Problem statement: Answer the multiple choice question.
Question: Which compound has a 4.233\% 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: COc1ccc(OC)c(CN2CCC(C(=O)N3CCN(c4ccccc4F)CC3)CC2)c1.O=C(O)C(=O)O
b: CC(C)OC(=O)Cn1nnc2c(cnn2-c2ccccc2)c1=O
c: O=C(NCc1ccccc1)c1ccc(=O)oc1
d: O=C1NC(=O)/C(=C\c2ccccc2OCc2cccc([N+](=O)[O-])c2)N1
e: O=C(CN(C(=O)Cn1nnc(-c2ccc(F)cc2)n1)c1cccc(F)c1)NC1CCCC1
Answer: c. O=C(NCc1ccccc1)c1ccc(=O)oc1
