Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 19.196\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: C=CCNC(=S)Nc1ccc(Cl)cc1F
b: CCCCOC(=O)c1cc(-c2ccc(/C=N/n3cnnc3)o2)ccc1Cl
c: Cc1cccc(-c2cnn(-c3cccc([N+](=O)[O-])c3)c2N)c1
d: O=C1Cc2ccccc2Sc2ccc(Cl)cc21
Answer: a. C=CCNC(=S)Nc1ccc(Cl)cc1F
