Task: Answer the multiple choice question.
Question: Which compound has a 20.560\% 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 additional words.
Options:
(a) NS(=O)(=O)c1ccc(CNC(=O)Cc2c(F)cccc2Cl)cc1
(b) COc1ccc(/C=N/NC(=O)C(C)Sc2ccccn2)cc1[N+](=O)[O-]
(c) COc1ccccc1NC(=O)CN1CCN(CC(=O)Nc2cc(NC(C)=O)ccc2OC)CC1
(d) CCCCSCCCNC(=O)c1cn(C)c2ccc(S(=O)(=O)N3CCCC3)cc2c1=O
Answer: a. NS(=O)(=O)c1ccc(CNC(=O)Cc2c(F)cccc2Cl)cc1
