Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -51.195% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a N/C(=N\OC(=O)COc1ccc(Br)cc1)c1cccc([N+](=O)[O-])c1
b CCN1C(=NCCc2cccnc2)N[C@@H](c2ccccc2)C(C(=O)OC)=C1C
c O=C(CSC(=S)N1CCCCC1)Nc1nc(-c2ccccc2)c(-c2ccccc2)o1
d Cc1ccc(NC(=O)COc2ccc(/C=C3/SC(=Nc4ccccc4)N(Cc4cccnc4)C3=O)cc2)cc1
Answer: b. CCN1C(=NCCc2cccnc2)N[C@@H](c2ccccc2)C(C(=O)OC)=C1C
