Task: Answer the multiple choice question.
Query: Which drug has a 2.103\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) COC(=O)NCc1ccc(S(=O)(=O)N2CCOCC2)cc1
(b) COCC(C)NC(=O)c1ccccc1OC(C)=O
(c) Cc1cc2c(N=NC(=O)C3CC3c3ccccc3)c(O)[nH]c2cc1Br
Answer: b. COCC(C)NC(=O)c1ccccc1OC(C)=O
