Task: Answer the multiple choice question.
Question: Which compound exhibits a -20.223% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cc1cc(/C=C2\SC(=O)NC2=O)c(C)n1-c1ccc(N2CCOCC2)cc1
b: O=C(CCCc1nc2ccccc2s1)NCc1ccccc1F
c: CSCCC(NC(=O)c1ccccc1Br)C(=O)NC(C)CCc1ccccc1
d: CCCNC(=O)c1ccc(N2CCC3(CC2)CC(c2cccc(Br)c2)=NO3)c(NC(=O)c2c(Cl)cccc2Cl)c1
Answer: b. O=C(CCCc1nc2ccccc2s1)NCc1ccccc1F
