Problem statement: Answer the multiple choice question.
Query: Which compound has a 16.920% 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, d, or e without using any additional words.
Options:
a: CCCCOC(=O)CSC1=C(C#N)C(c2cccnc2)C(C(=O)OCC)=C(c2ccccc2)N1
b: COc1ccc(NC(=O)Cn2nnc(-c3ccccc3NC(=O)C3CC3)n2)cc1
c: CCCC(=O)OCCn1c(Br)nc2c1c(=O)[nH]c(=O)n2C
d: Cc1ccc(-c2nc3cc(C)ccc3o2)cc1
e: CCc1ccccc1NC(=O)c1nnn(CC(=O)Nc2cccc(C)c2)c1N
Answer: c. CCCC(=O)OCCn1c(Br)nc2c1c(=O)[nH]c(=O)n2C
