Problem statement: Answer the multiple choice question.
Question: Which drug has a 19.886\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) O=C(O)CSc1cccc2cccnc12
b.) Cc1cc(C(=O)OCC(=O)Nc2cc(Cl)ccc2C)c(C)o1
c.) CCOC(=O)c1cnc2c(cnn2C)c1OC(CCNS(C)(=O)=O)C(F)(F)F
d.) Cc1cccc(NC(=O)CNC(=O)c2ccc(-n3cncn3)c([N+](=O)[O-])c2)c1C
Answer: c. CCOC(=O)c1cnc2c(cnn2C)c1OC(CCNS(C)(=O)=O)C(F)(F)F
