Problem statement: Answer the multiple choice question.
Question: Which compound has a 0.192\% 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.) CC1CCCC(C)N1C(=O)CCN1C(=O)C2C3C=CC(C3)C2C1=O
b.) O=C(COC(=O)c1ccc([N+](=O)[O-])cc1)NC1CCCC1
c.) O=[N+]([O-])c1ccc(N2CCN(CCO)CC2)cc1Sc1nc2ccccc2[nH]1
d.) COc1ccc(C(=O)NCCc2ccc(C)cc2)cc1OC1CCN(C(C)=O)CC1
Answer: c. O=[N+]([O-])c1ccc(N2CCN(CCO)CC2)cc1Sc1nc2ccccc2[nH]1
