Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.452\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) COC(=O)c1ccc(OCC(=O)Nc2ccsc2C(=O)OC)cc1
b) COc1ccc(NC(=O)CN2CCC(C(=O)c3ccc(C)cc3)CC2)c(OC)c1
c) Cc1ccc(C(=O)NNC2=NC(C)(C)Cc3ccccc32)cc1.Cl
Answer: a. COC(=O)c1ccc(OCC(=O)Nc2ccsc2C(=O)OC)cc1
