Task: Answer the multiple choice question.
Query: Which drug exhibits a -1.221% 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=C(O)CC/C(=C\c1cc([N+](=O)[O-])ccc1Cl)c1nc2ccccc2s1
b.) CC1CCCN(C(=O)CSc2nnc(-c3ccc(O)cc3)o2)C1
c.) Oc1cccc2c(NC(=S)Nc3ccc(SC(F)F)cc3)cccc12
Answer: a. O=C(O)CC/C(=C\c1cc([N+](=O)[O-])ccc1Cl)c1nc2ccccc2s1
