Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.286\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: Nc1ncnc(N(c2ccccc2)C2CCCCC2)c1[N+](=O)[O-]
b: CCOC(=O)C1=C(C)Nc2ncnn2C1c1ccccc1F
c: COc1ccc(C(=O)NCCC(=O)N2CCC3(CC2)NCCc2[nH]cnc23)cc1
Answer: b. CCOC(=O)C1=C(C)Nc2ncnn2C1c1ccccc1F
