Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.520\% 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 Cc1ccc(Cl)cc1NC(=O)c1cc(S(=O)(=O)N2CCOCC2)cn1C
b C=CCOC(=O)C1=C(C)Nc2ncnn2C1c1cc(Br)ccc1F
c O=S(=O)(CC(O)COc1ccc(Br)cc1)c1ccccc1
Answer: b. C=CCOC(=O)C1=C(C)Nc2ncnn2C1c1cc(Br)ccc1F
