Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.991\% 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. O=C1OC(c2ccc(Br)cc2)=N/C1=C\N1CCCCC1
b. Oc1c(Br)cc(Br)cc1CNc1ccccn1
c. CCOc1c(N2CC(C)OC(C)C2)c(=O)c1=O
d. O=C1CCCC2=C1C(c1ccco1)Nc1ccc(C(=O)c3ccccc3)cc1N2
e. CN(C)CCNC(=O)NC(=O)c1ccc(Cl)cc1
Answer: e. CN(C)CCNC(=O)NC(=O)c1ccc(Cl)cc1
