Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -3.355% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(N/N=C/c1cc([N+](=O)[O-])ccc1Cl)c1ccc2nc[nH]c2c1
(b) COC(=O)c1ccccc1NC(=O)CSc1nnc(-c2cccc(NC(C)=O)c2)n1C
(c) Nn1cnnc1SCC(=O)Nc1ccc(C2CCCCC2)cc1
Answer: a. O=C(N/N=C/c1cc([N+](=O)[O-])ccc1Cl)c1ccc2nc[nH]c2c1
