Step 1: Understanding professional misconduct.
Professional misconduct under the Advocates Act includes any act that violates duties to court, clients, or professional ethics.
Step 2: The case.
In Vikramaditya Vs. Smt. Jamila Khatoon, the advocate failed to appear before the court deliberately, causing harm to the client's case. The court held this amounts to misconduct.
Step 3: Eliminating wrong options.
- (A) Attending with firearms: Not part of this case.
- (C) Suppression of facts: Different context.
- (D) Defrauding client: Separate misconduct ground, not here.
Step 4: Conclusion.
Hence, the misconduct here was deliberate non-appearance (B).
