Problem statement: Answer the multiple choice question.
Question: Which drug has a -4.133\% 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 O=C(CCn1c(=O)[nH]c2ccccc2c1=O)N1CCN(c2ccc(Cl)cc2)CC1
b CC(=O)Nc1ccc(S(=O)(=O)NNC2=NS(=O)(=O)c3ccccc32)cc1
c O=C1NC2(CCCc3ccccc32)C(=O)N1Cc1nnc(-c2ccccc2Br)o1
Answer: a. O=C(CCn1c(=O)[nH]c2ccccc2c1=O)N1CCN(c2ccc(Cl)cc2)CC1
