Task: Answer the multiple-choice question.
Query: Which drug exhibits a 17.271\% 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 additional words.
Options:
a) CC(=O)c1c(C(C)=O)c(C)n(-c2nc(-c3cccs3)c(C)s2)c1C
b) O=S(=O)(c1cc(Cl)ccc1Cl)n1nnc2ccccc21
c) CC(C)OC(=O)C(C)Nc1ccc(F)c(Cl)c1
d) COc1cccc(OC)c1C(=O)Nc1nc2ccc(S(C)(=O)=O)cc2s1
Answer: a. CC(=O)c1c(C(C)=O)c(C)n(-c2nc(-c3cccs3)c(C)s2)c1C
