Task: Answer the multiple choice question.
Query: Which compound exhibits a 1.382\% 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: CC1=NN(/C(=N\c2nnc(C)s2)Nc2ccccc2)[C@H](c2cccc3ccccc23)S1
b: O=c1[nH]c(=S)n(CCC2=CCCCC2)c(O)c1/C=N/Nc1ccccc1
c: Cc1cc(F)ccc1NC(=O)c1cc(S(=O)(=O)N2CCOCC2)cn1C
Answer: a. CC1=NN(/C(=N\c2nnc(C)s2)Nc2ccccc2)[C@H](c2cccc3ccccc23)S1
