Task: Answer the multiple choice question.
Question: Which drug has a 7.511\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) CCCCNC(=O)CCCCC(=O)N/N=C/c1cccc(Cl)c1
b.) O=c1cnnc(N/N=C/C2CC=CCC2)[nH]1
c.) Nc1cc([N+](=O)[O-])ccc1Nc1ccccc1
Answer: a. CCCCNC(=O)CCCCC(=O)N/N=C/c1cccc(Cl)c1
