Why should genetically modified organisms be tested in a controlled environment?

Answer and explanation

Correct answer: To understand safety and effects

The correct answer is A: to understand safety and effects. Genetically modified organisms contain a deliberately changed genetic material, so their traits, benefits, and possible unintended effects must be studied carefully. A controlled environment limits uncontrolled spread and allows scientists to compare the modified organism with a suitable control under known conditions. They can observe growth, performance, interactions, and possible risks before wider use. Option A is correct because testing is meant to collect evidence about safety and effects. Option B is wrong because immediate release everywhere would remove careful control and could create ecological or health concerns. Option C is wrong because testing does not aim to remove the organism's DNA. Option D is wrong because the purpose is not always destruction; approved organisms may be useful after proper evaluation. Memory cue: test first, observe benefits and risks, then decide on responsible use.
