Task: Answer the multiple choice question.
Query: Which drug has a -4.631\% 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.) COc1ccc(CCNC(=O)c2ccc(Cl)c(S(=O)(=O)N3CCCC3)c2)cc1
b.) NNC(=O)CN1C(c2ccccc2Br)=Nc2ccc(Br)cc2C1c1ccccc1
c.) NS(=O)(=O)c1ccc(NC(=S)Nc2ccc(F)c(F)c2)cc1
Answer: a. COc1ccc(CCNC(=O)c2ccc(Cl)c(S(=O)(=O)N3CCCC3)c2)cc1
