Task: Answer the multiple choice question.
Query: Which drug has a 0.549\% 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) CCn1ncc(CNC(=O)c2cccc([N+](=O)[O-])c2)c1C
b) Cc1nn(C)cc1S(=O)(=O)Nc1ccc2c(c1)OCCO2
c) O=C(NCC1CCCCC1)c1cc(S(=O)(=O)N2CCOCC2)ccc1F
Answer: a. CCn1ncc(CNC(=O)c2cccc([N+](=O)[O-])c2)c1C
