Task: Answer the multiple-choice question.
Query: Which drug has a 6.955% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) CCOC(=O)C1=C(C)N(C)C(=S)N(C)C1c1ccc(OC)cc1
b) CCNc1sc(C(=O)OCC)c(N)c1C#N
c) O=C(O)[C@H](O)[C@@H](O)C(=O)O
Answer: b. CCNc1sc(C(=O)OCC)c(N)c1C#N
