Problem statement: Answer the multiple choice question.
Query: Which drug has a 3.885\% 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 COc1ccccc1Oc1nc(-c2ccccc2)cc(C)c1S(C)(=O)=O
b Cc1nn(Cc2c(Cl)cccc2Cl)c(C)c1NC(=O)CCCn1nc(C)c([N+](=O)[O-])c1C
c O=C(NNC1CC(=O)N(c2cccc(Cl)c2)C1=O)c1cccnc1
Answer: a. COc1ccccc1Oc1nc(-c2ccccc2)cc(C)c1S(C)(=O)=O
