Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 12.662\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C(CSc1nnc(CNc2ccc(F)cc2)o1)N1c2ccccc2Sc2ccccc21
b CCC(C)(CC(=O)N(C)CCC#N)c1ccccc1
c CC(=O)OC1C(OC(C)=O)N(C(C)=O)C(=O)N1C(C)=O
Answer: a. O=C(CSc1nnc(CNc2ccc(F)cc2)o1)N1c2ccccc2Sc2ccccc21
