Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 4.173\% 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 CCCCNS(=O)(=O)c1ccc(S(=O)(=O)NCc2ccncc2)cc1
b COc1ccc(Cl)cc1N1Cc2ccccc2C1
c CN(c1ccc([N+](=O)[O-])cc1/C=N/NC(=O)COc1ccccc1)C1CCCCC1
Answer: a. CCCCNS(=O)(=O)c1ccc(S(=O)(=O)NCc2ccncc2)cc1
