Step 1: Judge the Assertion by itself.
Clearing H. Pylori with a proper eradication regimen does two things that simple antacid treatment cannot, it heals the existing ulcer and cuts down future relapse rates sharply. This matches what is known about peptic ulcer management, so the Assertion stands as true.
Step 2: Judge the Reason by itself.
Calling H. Pylori the only cause of peptic ulcer ignores other well documented causes. NSAID use damages the stomach lining directly and is a leading cause of ulcers in people without H. Pylori infection. Zollinger Ellison syndrome, driven by a gastrin secreting tumour, is another rare but real cause. So the Reason is false.
Step 3: Compare the two.
A true Assertion paired with a false Reason means the Reason gives no valid support to the Assertion, it is simply wrong on its own terms.
Step 4: Remove the wrong codes.
Both options that need R to be true fail here. The option that needs A to be false also fails, since eradication therapy really is effective and disease specific in this way.
Final Answer:
The Assertion is true while the Reason is false.
