Task: Answer the multiple choice question.
Question: Which drug has a 3.745\% 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 COCC(C)Nc1nc(C)c(C(C)=O)s1
b O=C(CCl)N1CCN2C(=O)c3ccccc3C12c1ccc(Cl)cc1
c CCCN1C(=O)c2ccccc2NC1c1ccc(OC)cc1OC
Answer: a. COCC(C)Nc1nc(C)c(C(C)=O)s1
