Task: Answer the multiple choice question.
Query: Which compound has a -20.173% 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 other words.
Options:
a C=CCN1C(=O)NC(c2ccc(OC)cc2)(C(F)(F)F)S/C1=C(\C#N)c1nnc(N2CCOCC2)n1-c1ccccc1
b CCOC(=O)C1(Cc2ccccc2Cl)CCN(C(=O)c2cnccn2)CC1
c COC(=O)c1[nH]c2ccccc2c1NC(=O)CN1CCN(c2cccc(Cl)c2)CC1
d COc1ccccc1NC(=O)Cc1nnc(SCC(=O)Nc2ccc(F)cc2F)n1C
e CC(C)NC(=O)N(O)C1N(C(C)C)C(=O)N(Cc2ccc3c(c2)OCO3)C1(C)C
Answer: b. CCOC(=O)C1(Cc2ccccc2Cl)CCN(C(=O)c2cnccn2)CC1
