Task: Answer the multiple-choice question.
Question: Which compound exhibits a 19.724\% 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 C/C(N)=C(/C#N)C(=O)CSc1nnnn1-c1ccc(C)cc1C
b CC1CN(CCCCOc2ccc(F)cc2)CC(C)O1.O=C(O)C(=O)O
c CCOc1ccc(C2C(C(=O)c3ccco3)=C(O)C(=O)N2CCCn2ccnc2)cc1OC
d CCCCn1c(N)c(N(CC)C(=O)c2ccccc2F)c(=O)[nH]c1=O
Answer: d. CCCCn1c(N)c(N(CC)C(=O)c2ccccc2F)c(=O)[nH]c1=O
