Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.492\% 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:

b: CC(=O)N1CCOc2ccc(S(=O)(=O)NCCc3ccccc3)cc21
c: COC(CNS(=O)(=O)c1ccc(S(=O)(=O)NC2CC2)cc1)OC
d: Cc1cccc(N2CCN(C(=O)c3ccc4c(c3)OCCO4)CC2)c1C
e: CNC[C@H](CC1CCCCC1)NC[C@H](CO)NCC1(c2ccccc2)CC1
Answer: e. CNC[C@H](CC1CCCCC1)NC[C@H](CO)NCC1(c2ccccc2)CC1
