AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Defection means changing party allegiance from the party on which a person got elected to a different party.
A law was made to prevent it because many elected MLAs and MPs were changing parties to become ministers or for cash rewards. The law now states that if any MLA or MP changes parties, he/she will lose the seat in the legislature.

The question has two parts — definition (1 mark) and reason for the law (1 mark). Use the textbook definition directly. For the reason, mention both the cause (ministers/cash rewards) and the consequence stated in law (loss of seat). Keep it concise; no elaboration needed for 2 marks.
