Problem statement: Answer the MCQ question.
Question: Which drug has a 3.219% hERG inhibition at a concentration of 10uM?
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(CSc1ccc(Cl)cc1)Nc1ccc(-c2nc3ccccc3[nH]2)cc1
(b) Cc1c(-c2ccco2)[n+](=O)c2c(n1[O-])CCC2
(c) C=CCNCCCCOc1ccc(OCc2ccccc2)cc1.O=C(O)C(=O)O
(d) Nc1cn(C2OC(CO)C(O)C2O)c(=O)[nH]c1=O
(e) Cc1nc(-c2cccnc2)sc1C(=O)Nc1ccc(F)cc1F
Answer: b. Cc1c(-c2ccco2)[n+](=O)c2c(n1[O-])CCC2
