Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.506% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
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-])c1cccn2cc(-c3ccc(Br)cc3)nc12
b: CCCOC(=O)COC(=O)c1ccccc1NC(=O)c1ccccc1
c: CCCCCn1c(SCC(=O)OCC)nc2cc(C(=O)NCc3ccco3)ccc2c1=O
d: Cc1ccc(OCCOc2cccc(Br)c2)c([N+](=O)[O-])n1
Answer: c. CCCCCn1c(SCC(=O)OCC)nc2cc(C(=O)NCc3ccco3)ccc2c1=O
