Task: Answer the multiple choice question.
Question: Which compound exhibits a -0.681\% 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(N/N=C\c1cc2c(cc1Cl)OCO2)c1cccnc1
b O=C(Cn1nnc(-c2ccc(OCc3ccccc3F)cc2)n1)N1CCOCC1
c O=[N+]([O-])c1ccc2c(c1)C=C1CCCCC1(N1CCCCC1)O2
d CN(C)CCNC(=O)c1ccc(CS(=O)(=O)c2ccc(Br)cc2)o1
Answer: b. O=C(Cn1nnc(-c2ccc(OCc3ccccc3F)cc2)n1)N1CCOCC1
