Task: Answer the multiple-choice question.
Query: Which drug has a 15.553\% 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, c, or d without using any other words.
Options:
a O=C(Nc1ccccc1Sc1ccccc1)c1ccccc1
b CC(=O)CCC(=O)OCC(=O)c1ccc(C(F)(F)F)cc1
c CC(C)(C)C(=O)NNC(=O)CCCOc1ccc(Cl)cc1Cl
d CCOc1ccc(Cl)cc1S(=O)(=O)NCc1cccnc1
Answer: c. CC(C)(C)C(=O)NNC(=O)CCCOc1ccc(Cl)cc1Cl
