Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -22.955% 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(c1ccccc1)C1CCN(CC(=O)N2CCN(c3ccccc3)CC2)CC1
[b] O=C(NCCc1ccccn1)c1nc(Cn2cc([N+](=O)[O-])cn2)no1
[c] CCc1ccc(-c2ccc3nnc(SC)n3n2)cc1
Answer: c. CCc1ccc(-c2ccc3nnc(SC)n3n2)cc1
