Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.371\% 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 other words.
Options:
a.) CCOc1ccc(-c2cc(C(=O)N3CCN(c4ccccn4)CC3)c3ccccc3n2)cc1
b.) COc1ccc(Cn2ccnc2)cc1[N+](=O)[O-]
c.) CCN(CC)c1ccc(CNC(=O)C/C(C)=N/NC(=O)COc2ccc(C)cc2Br)cc1
d.) O=C1c2ccccc2C2NC(=O)C3(CCCCC3)N12
e.) CN(C)CCCN(Cc1ccccc1)C(=S)Nc1ccc(F)c(Cl)c1
Answer: d. O=C1c2ccccc2C2NC(=O)C3(CCCCC3)N12
