Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 12.486\% 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) O=C(N[C@@H](Cc1ccc(O)cc1)C(=O)O)C(c1ccccc1)c1ccccc1
(b) CCN1C(=O)N[C@@H](c2ccco2)C(C(C)=O)=C1C
(c) Cc1ccc(S(=O)(=O)N2CCC(C(N)=O)CC2)cc1[N+](=O)[O-]
Answer: a. O=C(N[C@@H](Cc1ccc(O)cc1)C(=O)O)C(c1ccccc1)c1ccccc1
