Task: Answer the multiple choice question.
Query: Which compound exhibits a 20.571\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a O=C(CN1CCN(S(=O)(=O)/C=C/c2ccccc2)CC1)Nc1ccc(N2CCOCC2)cc1
b CCc1c(-c2ccccc2)nc(N)c(C#N)c1-c1cccs1
c CC(C)(C)OC(=O)N1CCC(Cc2cc(-c3cccnc3)no2)(C(=O)O)CC1
d Cn1c(SCC(=O)NCc2cccs2)nnc1-c1ccncc1
e O=C(Nc1cccc(O)c1)c1cc(-c2ccco2)on1
Answer: a. O=C(CN1CCN(S(=O)(=O)/C=C/c2ccccc2)CC1)Nc1ccc(N2CCOCC2)cc1
