Task: Answer the multiple-choice question.
Question: Which compound has a -5.699\% 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 other words.
Options:
a.) O=C(c1ccc2nc(N3CCOCC3)sc2c1)N1CCN(C(=O)c2ccco2)CC1
b.) CN1C(C(=O)Nc2ccccn2)=C(O)c2sc(Cl)cc2S1(=O)=O
c.) COC(=O)c1cc(NC(=O)c2cccc(C(F)(F)F)c2)c(=O)oc1C/C=N/OCc1cccc(Cl)c1Cl
d.) CCCNC(C)(C)COC(=O)c1ccccc1.Cl
Answer: a. O=C(c1ccc2nc(N3CCOCC3)sc2c1)N1CCN(C(=O)c2ccco2)CC1
