Dear Student,
The representative elements are referred to the elements of 5 and p-block elements, while f- block considerably Z = 21-30, 39-48, 57 and 72-80, 89 and 104-112 are termed as transition elements in other hand Z = 58-71, 90-103 are called as inner transition elements.
3 = Group 1, 33= Group 15, 53 = Group 17 and 87 = Group 1
Hence the answer is Option (c) 3, 33, 53, 87
Regards.
