Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 0.106\% 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 CCN(CC)C(=O)c1sc2[nH]c(=S)n(-c3ccccc3)c(=O)c2c1C
b CCCOC(=O)C1=C(C)NC2=C(C(=O)C(C(=O)OC)C(C)C2)C1c1ccc(N(C)C)cc1
c CC(=O)/C(=N/Nc1cccc(Cl)c1)N1CCOCC1.Cl
d CC(C)c1cc(Br)ccc1OCCCN1C(=O)NC(C)(C)C1=O
e O=C(NCCN1CCOCC1)Nc1ccc(Cl)cc1Cl
Answer: e. O=C(NCCN1CCOCC1)Nc1ccc(Cl)cc1Cl
