Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.146\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a NNC(=O)CN(CCc1ccccc1)S(=O)(=O)c1ccc(Cl)cc1
b O=C(Nc1ccc(Br)cc1)NC1CCCCCCC1
c CCCCS(=O)(=O)N1CCN(S(=O)(=O)c2ccc(Cl)s2)CC1
Answer: c. CCCCS(=O)(=O)N1CCN(S(=O)(=O)c2ccc(Cl)s2)CC1
