Task: Answer the multiple choice question.
Question: Which compound exhibits a 7.826\% 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: N#Cc1c(NC(=O)C2CC(Cl)=CCC2C(=O)O)sc2c1CCCC2
b: COc1cc(OC)c(OC)cc1/C=N/NC(=O)C[n+]1ccccc1.[Cl-]
c: Cc1[nH]n(-c2ccc([N+](=O)[O-])cc2)c(=O)c1C=NCCN1CCN(C(=O)c2ccc(Br)cc2)CC1
d: CN1CCN(C(=O)CCn2nc(-c3ccccc3)c3ccccc3c2=O)CC1
e: CC1=CC(c2ccc(Cl)cc2)n2nc(N3C(=O)CCC3=O)nc2N1.O=C(O)CCC(=O)O
Answer: d. CN1CCN(C(=O)CCn2nc(-c3ccccc3)c3ccccc3c2=O)CC1
