Correct Answer:
B. Valid
Valid is the correct answer. Unless a specific law or rule explicitly prohibits proceedings from being held on holidays, such proceedings are generally considered legally valid. The principle is that administrative or judicial functions should not be unduly hampered by public holidays unless there's a clear statutory restriction.
- Prohibited is incorrect as there's no general prohibition.
- Conditionally valid is vague; validity is usually absolute unless a specific condition for invalidity is met.
- Re-inquired implies a default need for review, which is not the case for valid proceedings.
