Task: Answer the multiple choice question.
Query: Which compound exhibits a 12.673\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CCc1sc(C(=O)Nc2ccsc2C(=O)OC)cc1Br
b) S=c1nc(-c2ccc(Br)cc2)[nH]c2ccccc12
c) CC(OC(=O)/C=C/c1ccccc1)C(=O)Nc1ccc2c(c1)OCCO2
Answer: b. S=c1nc(-c2ccc(Br)cc2)[nH]c2ccccc12
