Lysosome is the membrane bound organelle in eukaryotic cells containing hydrolytic enzyme such as lipases, nucleases, proteases, galactosidase and e.t.c
The digestive enzyme of lysosome are produced from ER (endoplasmic reticulum) and then in golgi apparatus the membrane bound vesicles are formed which is called primary lysosome which contains inactive enzyme and after the formation of mature vesicle the inactive enzyme is activated based on PH of lumen of lysosome which is slightly acidic.
So, for your above questions the correct statement is.
a) they are initially inactive
b) they are synthesized in ER
This two statement is true , they can also activated by fusion with large acidic vesicles . And they does not required ATP or energy.
Hence only 1st two statement is correct.

Select the true statements about zymogens. Proteolytic enzymes are initially synthesized as zymogens to prevent off‑target activity. Activation of zymogens through proteolytic cleavage is a reversible process. Zymogens are inactive precursors that are cleaved to activate an enzyme. Proteolytic cleavage at a specific site on the zymogen causes conformational changes that expose the active site of the enzyme. Protease enzymes are the only enzymes activated by proteolytic cleavage.

Which of the following statements about enzymes are true? Select all that apply: Enzymes increase reaction rates by lowering the energy of the products. Enzymes increase the rate at which products are created by preventing reactions from running backwards. Enzymes increase reaction rates by lowering the activation energy of a reaction. Enzymes increase reaction rates by interacting with the substrate molecules to facilitate the reaction, for example by contorting them to facilitate bond-breakage or orienting them to favor bond formation.
