Correct answer: C. The Wooden and Iron tables would belong to different groups.लकड़ी और लोहे की मेजें अलग-अलग समूहों में होंगी।
Explanation
A magnet attracts iron (a magnetic material) but not wood (non-magnetic). So with this property the iron table goes into the attracted group and the wooden table into the non-attracted group, i.e. they belong to different groups. Option 2 states it the wrong way round.चुम्बक लोहे (चुम्बकीय पदार्थ) को आकर्षित करता है, लकड़ी (अचुम्बकीय) को नहीं। अतः इस गुण से लोहे की मेज आकर्षित होने वाले समूह में और लकड़ी की मेज न आकर्षित होने वाले समूह में आएगी, अर्थात् दोनों अलग-अलग समूहों में होंगी। विकल्प 2 उल्टी बात कहता है।More Environmental Studies (EVS) questions
