Why does a bill not become law without the President's assent?

Correct answer: Because a bill needs formal constitutional assent to become law

Direct answer: A. A bill is a proposed law. After it has been passed by the required Houses of Parliament, it must receive the President’s assent as part of the constitutional law-making procedure before it becomes an Act. This formal step confirms that the legislative process has reached its constitutional completion. A is correct because presidential assent is a required stage, although the President acts within constitutional rules and may have limited options depending on the type of bill. B is wrong because the President does not personally write every bill; bills are introduced and debated through the legislative process. C is wrong because Parliament does make laws on subjects within its constitutional authority. D is wrong because ministers do not always stop laws; ministers normally introduce or support government bills and remain accountable to Parliament. A useful distinction is that a bill is a proposal, while an Act is a law after the required procedure is completed. Memory cue: “Bill plus parliamentary passage plus assent becomes law.”
