Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 6.185\% 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 additional words.
Options:
a: O=[N+]([O-])c1ccc2c(c1)nc1n2CCSC1
b: CCOc1ccccc1C(=O)Nc1cc(=O)n(C)c(=O)n1C
c: COc1ccc(C)cc1NC(=O)CNC(C)C(=O)Nc1cc(Cl)ccc1Cl
d: CCCn1c(=O)c(C(=O)Nc2c(C)n(C)n(-c3ccccc3)c2=O)c(O)c2ccccc21
Answer: c. COc1ccc(C)cc1NC(=O)CNC(C)C(=O)Nc1cc(Cl)ccc1Cl
