Task: Answer the multiple choice question.
Query: Which compound has a 4.550\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) COc1ccnc(CSC(N)=Nc2ccc(F)cc2)c1.Cl
b) O=C(Nc1cccc(C(F)(F)F)c1)Nc1ccon1
c) CCOC(=O)C1=C(CSc2nc3c(cc2C#N)CN(C)CC3)OC(N)=C(C#N)C1c1ccccc1
d) COc1ccc(C2(c3cccc(O)c3OC)CCN(C(C)=O)CC2)cc1O
Answer: c. CCOC(=O)C1=C(CSc2nc3c(cc2C#N)CN(C)CC3)OC(N)=C(C#N)C1c1ccccc1
