Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.947\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccc(OC)c(NC(=O)C2CC(C)=C(C)CC2C(=O)O)c1
b: COc1ccc(-c2coc3cc(OC4OC(CO)C(O)C(O)C4O)cc(O)c3c2=O)cc1
c: COC(=O)CSc1nc(NC(C)=O)nc(C)c1Br
Answer: b. COc1ccc(-c2coc3cc(OC4OC(CO)C(O)C(O)C4O)cc(O)c3c2=O)cc1
