Task: Answer the multiple-choice question.
Query: Which drug exhibits a -31.894\% 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.) Cc1ccc(CN2CCN(Cc3cccc4c3OCO4)CC2CCO)cc1
b.) O=C(N/N=C/c1ccc(Br)o1)/C(=C/c1ccc([N+](=O)[O-])cc1)NC(=O)c1ccccc1
c.) COc1ccc(/C(C)=N/NC(=O)CNC(=O)Cc2ccccc2)c(OC)c1
d.) Cc1ccnn1-c1ccc(C(=O)N2CCCN(S(=O)(=O)c3ccc(F)cc3)CC2)cc1
Answer: b. O=C(N/N=C/c1ccc(Br)o1)/C(=C/c1ccc([N+](=O)[O-])cc1)NC(=O)c1ccccc1
