Task: Answer the multiple choice question.
Query: Which compound exhibits a 16.618\% 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 or b without using any additional words.
Options:
[a] O=C(O)/C=C/c1ccc(-n2ccnc2)cc1
[b] COc1cc(C(c2sc3ncnn3c2O)N2CCN(c3ccccc3F)CC2)cc(OC)c1OC
Answer: a. O=C(O)/C=C/c1ccc(-n2ccnc2)cc1
