A type of constitution where the procedure for its amendment is enshrined in it is a

Step 1: Analyze the question The question asks about a constitution whose amendment procedure is written into the constitution itself. In other words, the document states how it can be changed, and that process is usually difficult.

Step 2: Explain the concept

• Rigid constitution: This has a special, strict amendment procedure written into the document. Examples are a two-thirds majority in the legislature, approval by state Houses of Assembly, or a referendum. The Nigerian 1999 Constitution (Section 9) is a good example, because it requires a two-thirds majority in the National Assembly and approval by at least 24 of the 36 State Houses of Assembly.
• Flexible constitution: This can be amended easily, often by an ordinary law passed by the legislature through a simple majority. The UK constitution is the usual example.
• Democratic constitution: This describes the system of government, which is based on popular participation. It says nothing about how the constitution is amended.
• Unwritten constitution: This is not codified in a single document. It rests on conventions, customs and several statutes, so it has no single enshrined amendment procedure.

Step 3: Solve The phrase "procedure for its amendment is enshrined in it" points to a written constitution that sets out a special, formal amendment process. That is the mark of a rigid constitution.

Step 4: Answer The correct option is B. rigid constitution.

Exam tip: Think "rigid = rules written in and hard to change" and "flexible = easy to change, like ordinary laws." If a question mentions a special procedure or a two-thirds majority, choose rigid.
