Solution
The correct option is B Position of isotopes
The isotopes should be given different position due to different weight but should have same position as have same properties. This was a drawback of Mendeleev's table; However as isotopes have same atomic number, they should have same place in table. Thus this drawback was easily overcame. Hence answer is option B.
