Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 10.146\% 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) N#Cc1ccccc1OCCN1C(=O)c2ccccc2C1=O
(b) O=C(Nc1ccccc1Cl)c1cccc(NC(=O)c2cccs2)c1
(c) CC(C)CN1CCN(Cc2cnc(-c3ccc(Cl)cc3)nc2)CC1CCO
(d) CCCCCC(=O)Oc1cccc(N2C(=O)C3CCCCC3C2=O)c1
(e) O=c1[nH]c(/C=C/c2ccccc2Cl)c([N+](=O)[O-])c(=O)[nH]1
Answer: e. O=c1[nH]c(/C=C/c2ccccc2Cl)c([N+](=O)[O-])c(=O)[nH]1
