Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 9.891\% 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. O=C(COC(=O)c1cccc(N2C(=O)C3CC=CCC3C2=O)c1)c1ccccc1
b. Cc1ccc(OCc2ccc(Br)cc2)c([N+](=O)[O-])n1
c. Cc1cccc(C2N(c3nccs3)C(=O)C3CCCN32)c1
d. O=C(COc1ccccc1)N1CCN(C2CC3CCC2C3)CC1
e. COc1ccc(N(CC(=O)Nc2cc(OC)ccc2OC)S(=O)(=O)c2c(C)noc2C)cc1
Answer: d. O=C(COc1ccccc1)N1CCN(C2CC3CCC2C3)CC1
