Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.470% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCOP(=O)(NC(=NC(C)c1ccccc1)NC(C)c1ccccc1)OCC
[b] Cc1ccc2cccc(OC(=O)N(C)c3ccccc3)c2n1
[c] COc1ccc(CNCc2cccc(OC)c2OC)cc1Br.O=C(O)C(=O)O
[d] Cc1cc(Nc2ccc(F)c(Cl)c2)n2nc(C)nc2n1
Answer: a. CCOP(=O)(NC(=NC(C)c1ccccc1)NC(C)c1ccccc1)OCC
