Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 5.939\% 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:
a: CCN1C(=O)/C(=C/C=C2/CCCN2C)OC1=S
b: CCOC(=O)C1=C(CSc2nc(-c3ccccc3)ccc2C#N)OC(N)=C(C#N)C1c1ccc(OC)cc1
c: CCOC(=O)c1sc(NC(=O)CSc2nc(C)cc(C(F)(F)F)n2)c(C#N)c1C
d: O=C(NCC1CCCO1)C1CCN(C(=O)c2ccc(Cl)cc2)CC1
e: COc1ccc(NC(=O)C(NC(C)=O)C(=O)NCc2ccccc2)cc1
Answer: a. CCN1C(=O)/C(=C/C=C2/CCCN2C)OC1=S
