Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.843\% 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: Cc1c(Cl)cccc1NC(=O)NN1CCN(C)CC1
b: O=c1c(Cl)c(Nc2cccc(Cl)c2)cnn1-c1nc2ccccc2s1
c: CC1COC(c2cccn2Cc2ccccc2Cl)=N1
d: C=CCOC(=O)C1=C[C@@H](c2ccc(Br)cc2)C[C@@H](OCCCCO)O1
e: Cc1ccc(C(=O)Nn2c(N)c(S(=O)(=O)c3ccc(C)cc3)c3nc4ccccc4nc32)cc1
Answer: c. CC1COC(c2cccn2Cc2ccccc2Cl)=N1
