At the time of arraignment, the court must inform the defendant that:

• A. He has the right to a Supporting Deposition to be filed in the charge of a simplified traffic information
• B. He may not be prosecuted on a misdemeanor complaint unless he consents, or the misdemeanor complaint is replaced by an information
• C. The conviction or plea would subject the defendant to suspension/revocation of license and registration
• D. He has the right to a public defender

Answer: (B)

At arraignment, the court must inform the defendant how the case will be charged and what procedural options are available. A key rule here is about how misdemeanors are prosecuted: a misdemeanor cannot go forward by a misdemeanor complaint unless the defendant consents to proceed by information, or the complaint is replaced by an information. This ensures the defendant understands that the government cannot lock in a more formal charging document without his agreement, or without converting the case to the information form.

That’s why this option is the best choice: it directly states the procedural condition tied to how a misdemeanor can be prosecuted, which is the kind of information the court is required to convey at arraignment. The other points—such as a requirement to file a supporting deposition, or automatic entitlement to a public defender, or a license suspension consequence—are either not universally mandated at arraignment or depend on separate circumstances (like indigence or the specific charges and penalties).
