Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 18.388\% 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: CC(=O)C[C@H]1c2cc(C(F)(F)F)ccc2S(=O)(=O)N1Cc1ccccc1
b: O=c1[nH]cc(-c2ccc(Br)cc2)n1Cc1ccccc1
c: CCN=C(NCC)SC1CC(=O)N(CCc2ccccc2)C1=O
Answer: c. CCN=C(NCC)SC1CC(=O)N(CCc2ccccc2)C1=O
