Task: Answer the multiple choice question.
Question: Which compound has a 3.674\% 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. NS(=O)(=O)c1ccc(CNC(=O)/C=C/c2cccc(Cl)c2)cc1
b. CCCCN(C(=O)c1ccc(C)c(S(=O)(=O)N2CCOCC2)c1)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
c. CCOc1cc(N2CCOCC2)c(OCC)cc1NC(=O)C(C)C
d. CCCOc1ccc(-c2c(C(=O)N/N=C/c3ccc(OC)cc3)nnn2-c2nonc2N)cc1
e. CCc1ccc(OCC(O)CN2CC(C)OC(C)C2)cc1.Cl
Answer: a. NS(=O)(=O)c1ccc(CNC(=O)/C=C/c2cccc(Cl)c2)cc1
