Mendeleev divided the periodic table into 8 groups, each divided into two sub-groups named as A and B. He arranged the elements according to their atomic masses.

Group A elements are considered as the elements which are present in s-block and p-block.

Group B elements are the transition elements. Transition elements are the elements that belong to d-block.

From the given elements:

Lithium (Group 1-A) and helium (Group VIII-A) are s-block elements.

Tellurium is a p-block (Group VI-A)element.

Uranium is a f-block element.

Iron is the d-block (Group VIII-B)element (transition element)

Hence, iron is considered as a Group B element.
