Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 16.821\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(Nc1scc(-c2ccccc2)c1C(=O)O)c1ccccc1F
b: Cc1cccc(NS(=O)(=O)c2cccc(C(=O)NNC(=O)c3ccccc3O)c2)c1
c: O=C(CSc1cccc[n+]1[O-])c1ccc(-c2ccccc2)cc1
d: Cc1cc(NS(=O)(=O)c2ccc(NC(=S)NC(=O)c3ccncc3)cc2)no1
e: CCOC(=O)CN1C(=O)C(O)=C(C(C)=O)C1c1ccc([N+](=O)[O-])cc1
Answer: a. O=C(Nc1scc(-c2ccccc2)c1C(=O)O)c1ccccc1F
