Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.971% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Clc1cccc(Cl)c1-c1nnc2ccc(N3CCOCC3)nn12
b: CCOC(=O)C1=C(CN2CCSCC2)NC(=O)NC1c1cc(C)ccc1C
c: O=c1oc2ccccc2c(N2CCCCC2)c1[N+](=O)[O-]
Answer: a. Clc1cccc(Cl)c1-c1nnc2ccc(N3CCOCC3)nn12
