Task: Answer the multiple-choice question.
Question: Which drug has a -20.949\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. CC(NC(=S)Nc1c(Br)cccc1OC(F)F)C(C)(C)C
b. CCCC(C)C(=O)Nc1ccc2c(c1)OCCO2
c. COC(/C=C/Nc1ccc(OC)cc1)=C(C#N)C#N
d. CC(=O)NC1=NN(C(C)=O)C(C)(c2ccc(C)o2)S1
e. COc1ccc(-c2nnc(SCC(=O)N3CCCC3)o2)cc1
Answer: c. COC(/C=C/Nc1ccc(OC)cc1)=C(C#N)C#N
