Task: Answer the multiple-choice question.
Query: Which compound exhibits a 21.451\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) Clc1ccc(-c2nnc(-c3ccccc3)nc2-c2c[nH]c3ccccc23)cc1
b.) COC(=O)c1cc(NC(=O)Cn2c(=O)oc3ccccc32)cc(C(=O)OC)c1
c.) O=C(NNC(=O)c1ccccc1F)c1ccc(-n2cncn2)c([N+](=O)[O-])c1
d.) COC(=O)C1=C(C)NC(=O)/C1=C\c1cc(C)n(-c2ccccc2)c1C
e.) CCN(CC)c1ccc(NC(=O)c2ccc(=O)[nH]c2)cc1S(=O)(=O)Nc1ccc(OC)cc1
Answer: d. COC(=O)C1=C(C)NC(=O)/C1=C\c1cc(C)n(-c2ccccc2)c1C
