Task: Answer the multiple-choice question.
Query: Which drug has a 12.327\% human ether-à-go-go related gene (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 other words.
Options:
a: CCc1n[nH]c(=O)c2cc3cc(OC)ccc3n12
b: CCOc1ccc(CNC(=O)CCS(=O)(=O)c2ccc3c(c2)oc(=O)n3C)cc1
c: C/C(=N\OCC(=O)Nn1c(=O)[nH]c2ccccc2c1=O)c1ccccc1
d: O=C(CSc1nc2ccccc2c(=O)[nH]1)Nc1cccc([N+](=O)[O-])c1
Answer: a. CCc1n[nH]c(=O)c2cc3cc(OC)ccc3n12
