Task: Answer the multiple choice question.
Question: Which compound exhibits a 20.073% 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 additional words.
Options:
a. COc1ccc(/C=C2/C(=O)ON=C2C)cc1Br
b. CC(C)OC(=S)N/C(=N\S(=O)(=O)c1ccccc1)c1ccccc1
c. O=S(=O)(c1ccc(Cl)cc1)N1CC1c1ccccc1
d. CC1CCCN(C(=O)C2C(C=C(Cl)Cl)C2(C)C)C1
Answer: a. COc1ccc(/C=C2/C(=O)ON=C2C)cc1Br
