AThree mutually intersecting circles
BMercury and zinc as two separate circles, both inside the metal circle ✓ Correct
CThree fully separate circles
DMetal inside mercury inside zinc
Correct answer: (B) Mercury and zinc as two separate circles, both inside the metal circle — The second diagram best fits, so that is the answer.
Explanation
★The second diagram best fits, so that is the answer.
★Mercury and zinc are two different metals, so they do not overlap each other.
★Both mercury and zinc are kinds of metal, so both lie fully within the group of metals.
★This is shown by two separate circles placed inside one larger metal circle.
★Intersecting or fully separate circles would misrepresent the relation.
★So the answer is mercury and zinc as separate circles inside the metal circle.
