Task: Answer the multiple-choice question.
Query: Which drug exhibits a 19.614% 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 C=CCNc1sc(C(=O)c2cccs2)c(N)c1C#N
b CCN(CC)C(=O)C1CCCN(c2ccc([N+](=O)[O-])cc2/C=N/NC(=O)c2ccccc2)C1
c OCc1ccnc2c(O)cccc12
Answer: a. C=CCNc1sc(C(=O)c2cccs2)c(N)c1C#N
