Task: Answer the multiple choice question.
Query: Which drug has a 4.862\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. C/C(N)=C(/C#N)C(=O)CSc1nc2cc(Cl)ccc2s1
b. C=CCN(C(=O)c1csnn1)C(C(=O)NC(C)(C)C)c1ccncc1
c. O=C(c1cc(C(=O)N2CCOCC2)c2nc3ccccc3n2c1)c1cc(Cl)cc(Cl)c1O
Answer: c. O=C(c1cc(C(=O)N2CCOCC2)c2nc3ccccc3n2c1)c1cc(Cl)cc(Cl)c1O
