Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 18.880\% 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: CCOc1ccc(OCC(=O)OCC(=O)NNC(=O)c2ccc([N+](=O)[O-])cc2)cc1
b: O=C(c1ccccc1O)N1N=C(C(F)(F)F)CC1(O)c1ccc([N+](=O)[O-])cc1
c: CCCC(=O)Nc1ccc(C(N)=O)cc1
d: O=C1C(C=NCc2ccncc2)=C(O)c2ccccc21
e: Cc1ccc(C)c(NC(=O)C2CCCN2C(=O)NC2CCCCC2)c1
Answer: c. CCCC(=O)Nc1ccc(C(N)=O)cc1
