Problem statement: Answer the multiple-choice question.
Question: Which compound has a -27.551\% 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.) O=C(CSc1nncs1)NC(=O)NC1CCCC1
b.) O=C(CN1CCCc2ccccc21)Nc1ccccc1[N+](=O)[O-]
c.) CC1=CC(C)(C)Nc2ccc(C)cc21
d.) CCOC(=O)N1CCC(NC(=O)c2ccc(Cl)cc2)CC1
e.) CCCCNC(=O)/C(C#N)=C/c1cccnc1
Answer: c. CC1=CC(C)(C)Nc2ccc(C)cc21
