Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.173\% 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 other words.
Options:
a. O=C(C1CCCCN1S(=O)(=O)c1ccccc1[N+](=O)[O-])N1CCOCC1
b. CCN(CC)CCNC(=O)c1ccc(NC(=O)c2ccc3c(c2)CCC3)cc1
c. C=CCn1c(SCc2ccccc2C#N)nnc1-c1cc(Br)ccc1O
d. CCN(CC)CCCNC(=O)c1ccc2c(Cl)c3c(nc2c1)CCCC3
e. C=CCNC(=O)COc1coc(CN2CCN(Cc3ccccc3)CC2)cc1=O
Answer: e. C=CCNC(=O)COc1coc(CN2CCN(Cc3ccccc3)CC2)cc1=O
