Task: Answer the multiple choice question.
Query: Which compound exhibits a 7.171\% 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. Cc1ccccc1C(=O)N1CCC(C(=O)N(CC(C)C)c2c(N)n(CC(C)C)c(=O)[nH]c2=O)CC1
b. COc1ccc(Nc2nccc(N(C)C)c2C#N)cc1
c. CC1CN(C2CC(C)(C)NC(C)(C)C2)CCC1=O
d. O=c1[nH][nH]cc1C=NCc1cccc(C(F)(F)F)c1
e. Cc1cccnc1NC(=O)CCc1c[nH]c2ccccc12
Answer: c. CC1CN(C2CC(C)(C)NC(C)(C)C2)CCC1=O
