Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.202\% 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 other words.
Options:
a) O=C(Cn1ncc2c3ccccc3n(Cc3ccc(F)cc3)c2c1=O)N1CCN(c2ncccn2)CC1
b) CN1CCN(CCC(=O)N/N=C/c2cc([N+](=O)[O-])ccc2O)CC1
c) COc1ccc(-n2c(=O)c3c4c(sc3n(Cc3cccc(F)c3)c2=O)CN(C(C)=O)CC4)c(OC)c1
Answer: a. O=C(Cn1ncc2c3ccccc3n(Cc3ccc(F)cc3)c2c1=O)N1CCN(c2ncccn2)CC1
