Task: Answer the multiple choice question.
Query: Which drug has a 16.529\% 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(Oc1cc2oc(=O)c3c(c2cc1Cl)CCCC3)c1cccs1
b.) Oc1ccc(N=Nc2ccc3c(c2)OCCO3)c2cccnc12
c.) Cc1ccc(C)c(CSc2nnc([C@@H](N)C(C)C)o2)c1.Cl
Answer: a. O=C(Oc1cc2oc(=O)c3c(c2cc1Cl)CCCC3)c1cccs1
