Which of the following is incorrect according to the Bar Council of India Rules?

The Bar Council of India Rules on standards of professional conduct and etiquette, framed under section 49(1)(c) of the Advocates Act, 1961, prohibit an advocate from acting or pleading in any matter in which he is himself pecuniarily interested, so "An Advocate can plead in any matter in which he is himself pecuniarily interested." is incorrect. The same rules do require that "An advocate shall appear in court at all times only in the prescribed dress.", that "An Advocate shall not stand as a surety for his client." and that "An Advocate shall not influence the decision of a court by any improper means."
