• A) Grow H. pylori in a test tube with glycoprotein that has its terminal NAG removed.
• B) Destroy the H. pylori by exposing them to a hypotonic solution. Then add the glycoprotein and observe.
• C) Expose other species of bacteria to the glycoprotein.
• D) Grow H. pylori in a test tube in vitro) with no glycoprotein.
