Task: Answer the multiple choice question.
Question: Which drug has a 7.564\% hERG inhibition at a concentration of 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(COC(=O)c1ccccc1Sc1ccc(C(F)(F)F)cc1[N+](=O)[O-])NC(=O)NC1CCCC1
b) CCc1ccc(OCCOCC(O)CNC(C)(C)C)cc1.Cl
c) Cc1ccc(NC(=O)COC(=O)C2CSC3(C)CCC(=O)N23)c(C)c1
d) COC(=O)c1cn(C(=O)c2ccc(OC)c(OC)c2)c2ccccc12
Answer: a. O=C(COC(=O)c1ccccc1Sc1ccc(C(F)(F)F)cc1[N+](=O)[O-])NC(=O)NC1CCCC1
