Task: Answer the multiple choice question.
Question: Which compound has a 7.688\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) O=C(Nc1ccccc1)N(C1=NCCC1)c1ccccc1
b.) O=C(CSc1ccc2nnc(-c3cccnc3)n2n1)NCc1ccc2c(c1)OCO2
c.) CCN1CCN(C(=O)C2=C(C(=O)O)CCCC2)CC1
d.) CCC(=O)c1cc2c(C)cc(=O)oc2c(C)c1OC(C)=O
Answer: c. CCN1CCN(C(=O)C2=C(C(=O)O)CCCC2)CC1
