Task: Answer the multiple choice question.
Question: Which compound exhibits a 15.655\% 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(CNC1CCCCCC1)Nc1ccc(N2CCCC2)cc1.O=C(O)C(=O)O
b N#Cc1ccccc1OCC(=O)NCc1ccccc1CN1CCCC1
c O=C(Nc1ccccc1F)c1ccc(Br)o1
d O=C(NCCc1cccs1)c1ccc(Cl)c(Cl)c1
e Cc1noc(C)c1COc1ccc(C(=O)OCC(=O)NCCN2C(=O)CSC2=O)cc1
Answer: c. O=C(Nc1ccccc1F)c1ccc(Br)o1
