Task: Answer the multiple choice question.
Query: Which drug has a 4.269\% 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 CCOC(=O)c1ccc(NC(=S)NNC(C)(C)C)cc1
b CCOc1ccc(CCNC(=O)Cn2ncn3nc(-c4ccc(OC)cc4)cc3c2=O)cc1OCC
c CC(=O)NCC(=O)NC1(C(=O)NC2CCCC2)CCCCC1
Answer: b. CCOc1ccc(CCNC(=O)Cn2ncn3nc(-c4ccc(OC)cc4)cc3c2=O)cc1OCC
