Task: Answer the multiple choice question.
Question: Which drug has a 18.478\% 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 O=C(CC12CCC(CC1)C2)NCc1ccc2c(c1)OCO2
b CCc1ccc2[nH]c(C(=O)Nc3ccc(F)cc3Br)cc2c1
c O=C(CNC1CCCCCC1)Nc1ccc(N2CCCC2)cc1.O=C(O)C(=O)O
d C=CCN1C(=O)C(Cc2cccc(C)c2)SC1=Nc1ccc(C(=O)O)cc1
Answer: b. CCc1ccc2[nH]c(C(=O)Nc3ccc(F)cc3Br)cc2c1
