Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.571\% 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 additional words.
Options:
a CC(C)C[C@H]1CN=C(Nc2ccccc2)N1CC1CCCCCC1
b CC(=O)NC(CC(=O)Nc1nc(C)cs1)c1ccccc1
c CCc1ccccc1NC(=O)/C(C#N)=C/c1ccc(Sc2ccccc2)o1
d O=C(OCc1nnc(-c2ccccc2)o1)c1ccc(CO)cc1
e Cc1cc(NC(=O)CSc2nc(N)c(NC(=O)c3ccccc3F)c(=O)[nH]2)no1
Answer: c. CCc1ccccc1NC(=O)/C(C#N)=C/c1ccc(Sc2ccccc2)o1
