Task: Answer the multiple choice question.
Query: Which drug has a -4.852\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CCCn1c(C)cc(C(=O)COc2ccc(S(=O)(=O)N(CC)CC)cc2[N+](=O)[O-])c1C
b Cc1cc(OCC(O)CN2CCc3ccccc3C2)ccc1Cl.Cl
Answer: a. CCCn1c(C)cc(C(=O)COc2ccc(S(=O)(=O)N(CC)CC)cc2[N+](=O)[O-])c1C
