Task: Answer the multiple choice question.
Query: Which drug has a 19.327\% 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, or c without using any additional words.
Options:
a: CC(Oc1ccccc1Cl)C(=O)/C=C/N(C)C
b: COc1cc(C)c(S(=O)(=O)n2nnc3ccccc32)cc1C
c: Clc1ccc(-c2nnc(C3CCCCC3)o2)cc1
Answer: a. CC(Oc1ccccc1Cl)C(=O)/C=C/N(C)C
