Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.496\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CCOc1ccccc1Nc1ccc(C(=O)O)cc1NC(C)=O
b: Cc1cc(Oc2nc3c(C)cccn3c(=O)c2/C=C(\C#N)S(=O)(=O)c2ccc(Cl)cc2)ccc1Cl
c: Cc1cc(Cl)c2oc(C(=O)N(C)CCCN3CCOCC3)c(C)c2c1
Answer: b. Cc1cc(Oc2nc3c(C)cccn3c(=O)c2/C=C(\C#N)S(=O)(=O)c2ccc(Cl)cc2)ccc1Cl
