Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.751\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=[N+]([O-])c1cccc(CN2CCN(S(=O)(=O)Cc3ccccc3)CC2)c1
(b) COC(=O)CSc1nnc(CNC(=O)c2ccc(S(=O)(=O)N3CCCCC3)cc2)n1C
(c) O=C(Cn1cnc2sc(-c3ccccc3)cc2c1=O)NCc1ccccc1
Answer: a. O=[N+]([O-])c1cccc(CN2CCN(S(=O)(=O)Cc3ccccc3)CC2)c1
