Wait, the user provided the correct answer as B. So maybe the options are labeled differently. Let me look again. The options are a) to e), and the correct answer is B. Wait, maybe the options are labeled A to E, and the correct answer is B. Let me confirm.
The user's question says "Correct Answer: [Letter]." The options are a) to e), and the correct answer is B. So the correct answer is option B: Recurrent ulcers. But wait, aphthous ulcers are indeed recurrent. Let me verify each option.
Option a) Viral predisposition: Aphthous ulcers are not caused by a virus. They are of unknown etiology, sometimes linked to stress, trauma, or nutritional deficiencies. So a) is incorrect.
Option b) Recurrent ulcers: Yes, they are known to recur, so this is correct.
Option c) Deep ulcers: Aphthous ulcers can be deep, especially larger ones (major aphthous ulcers), so c) might be correct. However, some sources say they are superficial. Wait, need to check that. Minor aphthous ulcers are small and shallow, while major ones are larger and deeper. So c) is correct for major aphthous ulcers.
Option d) Involves the mucosa of the hard palate: Aphthous ulcers typically occur on non-keratinized mucosa (like the cheeks, tongue, lips), not the hard palate, which is keratinized. So d) is incorrect.
Option e) Steroids given as treatment: Topical corticosteroids are used for treatment, especially for larger ulcers, so e) is correct. But wait, the options in the question are a) to e), and the correct answer is B. Wait, maybe the options are labeled A to E, and the correct answer is B. So the user's correct answer is B. But if the options are a) to e), and the correct answer is B, that would be option b) Recurrent ulcers. But the other options like c) and e) might also be correct. Wait, the user's correct answer is B, but the options may have multiple correct answers. However, the question is phrased as "True about aphthous ulcer" and the options are a) to e), so perhaps it's a single correct answer. Wait, the original question is in the Indian format where sometimes multiple options can be correct but the user's correct answer is B. Let me check again.
If the correct answer is B, then the other options (c and e) must be incorrect. But wait, steroids are used in treatment, so e) is correct. So maybe the question is a single answer, and the options are a to e, but the correct answer is B. Therefore, the other options are incorrect. Let me check each again.
Option a) Viral predis
