Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.696\% 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 additional words.
Options:
a: O=C(CNC(=O)c1cccc(F)c1)N/N=C/c1cccc([N+](=O)[O-])c1
b: N#Cc1c(N)nc2c(c1-c1ccccc1)CCCC2
c: Cc1noc(C)c1CSCC(=O)N(CCC(C)C)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
d: CC1CN(c2ccnc3cc(Cl)ccc23)CC(C)O1
Answer: d. CC1CN(c2ccnc3cc(Cl)ccc23)CC(C)O1
