Task: Answer the multiple choice question.
Question: Which drug exhibits a -8.673% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(NC1CCCC1)c1ccc(Br)s1
b) COC(=O)c1sc2nc(C)cc(-c3ccccc3)c2c1N
c) Cc1ccc(OCC(=O)Nc2ccc(F)cc2)cc1C
Answer: a. O=C(NC1CCCC1)c1ccc(Br)s1
