Task: Answer the multiple-choice question.
Question: Which compound has a 1.311\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) O=C(COc1ccc(F)cc1Cl)Nc1cccc(S(=O)(=O)N2CCCCCC2)c1
b.) CC(C)N=C(NC#N)SCc1ccccc1F
c.) COc1ccc(OC)c(-n2c(O)c(/C=C3\C=Nc4ccccc43)c(=O)[nH]c2=O)c1
d.) O=S(=O)(c1ccc2c(c1)OCCO2)N1CCC(n2cnc3cc(F)ccc32)CC1
e.) O=C(N1CCN(c2ncccn2)CC1)C12CC3CC(CC(C3)C1)C2
Answer: b. CC(C)N=C(NC#N)SCc1ccccc1F
