Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.670% 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) Cc1cc(=O)[nH]c(N/N=C/c2c(C)nn(-c3ccccc3Cl)c2Cl)n1
(b) Cc1ccc(CN2C(=O)C(C)Nc3ncnc(N4CCOCC4)c32)cc1.O=C(O)C(F)(F)F
(c) Cc1ccc(N=C2C(=O)Nc3ccccc32)c(C)c1
Answer: a. Cc1cc(=O)[nH]c(N/N=C/c2c(C)nn(-c3ccccc3Cl)c2Cl)n1
