Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.630\% 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 other words.
Options:
a.) COc1ccc(NS(=O)(=O)c2ccc(-n3cc(C(=O)c4cc(Cl)ccc4O)cn3)c([N+](=O)[O-])c2)cc1
b.) CCOC(=O)c1c(NC(C)=O)sc2c(O)c(Br)ccc12
c.) Cc1nn(-c2ccc(F)cc2)c(Cl)c1/C=C(\CC(=O)O)c1nc2ccccc2s1
d.) Cc1cnc(C(=O)OCC(=O)Nc2ccc(C)c(S(=O)(=O)N3CCCCCC3)c2)cn1
Answer: b. CCOC(=O)c1c(NC(C)=O)sc2c(O)c(Br)ccc12
