Task: Answer the multiple choice question.
Query: Which drug has a -68.470% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C1C2C3c4ccccc4C(c4ccccc43)[C@@H]2C(=O)N1c1ccccn1
b: Cc1cccc(Cn2c(O)c(N=NC(=S)Nc3ccccc3F)c3ccccc32)c1
c: Cc1c(C(=O)NNC(=O)c2ccncc2)oc2ccc(Br)cc12
Answer: c. Cc1c(C(=O)NNC(=O)c2ccncc2)oc2ccc(Br)cc12
