please answer the three multiple choice questions regarding the drug structure below

Drug Structure 3. You treat the drug above with a 5 points protease which of the following statement concerning the dominant drug species is correct? Treatment results in two products with one product having a formal charge of 2 at pH5, while the second product has a formal charge of +1 at pH5. Treatment results in two products with one product having a formal charge of 2 at pH7, while the second product has a formal charge of +1 at pH7. Treatment results in two products with one product having no formal charge at pH2, while the second product has a formal charge of +1 at pH2. Treatment results in two products with one product having a formal charge of -2 at pH9, while the second product has a+2 formal charge at pH9.
