Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -0.711\% human ether-à-go-go related gene (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: COc1ccccc1NC(=S)NN1CCN(C)CC1
b: O=C(COC(=O)c1nc(Cl)ccc1Cl)NC(=O)c1ccccc1
c: O=C(Nc1ccccc1)c1cnc(-c2ccccc2)nc1-c1ccccc1
d: COc1ccc([N+](=O)[O-])cc1NC(=O)c1ccc(N(Cc2ccccc2Cl)S(C)(=O)=O)cc1
Answer: b. O=C(COC(=O)c1nc(Cl)ccc1Cl)NC(=O)c1ccccc1
