Final answer:
The question pertains to the required security deposit for a Comprehensive License (CL) holder with 8 or more demerit points. However, without specific jurisdictional information, it is not possible to provide an exact amount for the security deposit as these regulations vary by location.
Step-by-step explanation:
The question relates to the specific rules and regulations surrounding a Comprehensive License (CL) for drivers and the security deposits associated with demerit points accumulated over a period of time. Typically, such regulations would be a matter of administrative policy within the Department of Motor Vehicles (DMV) or a similar licensing authority. Since the question is asking for the amount of the required security deposit (SD) after accruing a certain number of demerit points, it falls under business or law, specifically in the realm of licensing regulations and financial penalties.
However, the exact amount of the security deposit cannot be provided without more context or reference to the specific regulations of the jurisdiction in question. Licensing regulations differ widely from one place to another, and there is no universal rule for security deposits related to demerit points on driving licenses. To provide a precise answer, one would need to refer to the statutes or administrative codes that apply to the particular area where the comprehensive license is issued.
