Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 2.469\% 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, or d without using any other words.
Options:
a: Nn1c(COc2ccccc2F)nnc1SCC(=O)NC1CCS(=O)(=O)C1
b: O=C(NCCc1nc2ccccc2[nH]1)/C(=C/c1ccco1)NC(=O)c1ccc(Br)cc1
c: O=C(Nc1ccc2c(c1)CCC2)c1cnc(Cl)c(Cl)c1
d: O=C(CCn1c(=O)c2cccn2c2ccccc21)Nc1ccc(F)cc1
Answer: c. O=C(Nc1ccc2c(c1)CCC2)c1cnc(Cl)c(Cl)c1
