Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 3.162\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. COC(=O)Nc1c(-c2ccccc2)nc2ccc(C)cn12
b. CCOC(=O)c1cc(C)n(-n2cnnc2)c1C
c. O=C(CSc1ccc(-c2cccc([N+](=O)[O-])c2)nn1)N1CCCCCC1
Answer: a. COC(=O)Nc1c(-c2ccccc2)nc2ccc(C)cn12
