Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a -1.526\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. O=C(Nc1ccon1)c1sc2ccccc2c1Cl
b. CCc1ccc(/C(C)=N/NC(=O)c2ccc(-n3cnnn3)cc2)cc1
c. COc1ccc(CCNC(=O)C(C)n2nc(C)n3c(cc4occc43)c2=O)cc1OC
d. C[NH+]1CCC2(CC1)C(C#N)=C(N)NC([S-])=C2C#N
Answer: d. C[NH+]1CCC2(CC1)C(C#N)=C(N)NC([S-])=C2C#N
