Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 12.053\% human ether-à-go-go related gene (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=S(=O)(NCc1csc(-c2cccs2)n1)c1ccc(Cl)cc1
(b) COc1ccc(-n2nc(C(=O)NCC(=O)NCC3CCCO3)c3ccccc3c2=O)c(OC)c1
(c) CCN(CC)S(=O)(=O)c1ccc(Cl)c(C(=O)Nc2ccc(Cl)cc2[N+](=O)[O-])c1
Answer: a. O=S(=O)(NCc1csc(-c2cccs2)n1)c1ccc(Cl)cc1
