Task: Answer the multiple choice question.
Question: Which drug exhibits a -12.804\% 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, or c without using any additional words.
Options:
a) CCOC(=O)c1cnc(-n2nc(C)cc2C)[nH]c1=O
b) O=C(/C=C/c1ccc(Cl)cc1)N1CCN(Cc2ccccc2)CC1
c) COc1ccc(CCNC(=O)C(=O)c2cn(CC(=O)N3CCOCC3)c3ccccc23)cc1
Answer: b. O=C(/C=C/c1ccc(Cl)cc1)N1CCN(Cc2ccccc2)CC1
