Task: Answer the multiple choice question.
Question: Which drug exhibits a 20.389\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) C=CCCC(=O)Nc1ccc(COC(=O)N2CCOCC2)cc1
b.) Cc1nnsc1NC(=O)OCC(C)C
c.) C[C@@H](C(=O)Nc1ccc2ccccc2c1)[C@@H]1C[C@@]1(C)[C@@H](NC(=O)c1cnccn1)c1ccccc1
d.) COc1ccc(CN2C(=O)NC(=O)/C(=C\c3ccc(OC)c(OC)c3OC)C2=O)cc1
e.) COc1cc(CNc2ccc(O)cc2)cc(Br)c1OCc1ccccc1
Answer: e. COc1cc(CNc2ccc(O)cc2)cc(Br)c1OCc1ccccc1
