The correct answer to the question is : Sc, Ti, V, Cr, Mn.
EXPLANATION:
The given element is iron (Fe).
The atomic number of iron is 26 in the periodic table. It is a transition element which is present at the first transition series i.e in the third row or period in the modern periodic table.
The other transition elements that come in this series before iron is scandium ( Sc), titanium ( Ti), vanadium ( V), chromium ( Cr) and manganese ( Mn) in the periodic table.
There is other two elements that come in the third row which are known as potassium and calcium. But these are not transition group elements.
Hence, the correct answer of this question is Sc, Ti, V, Cr and Mn respectively.
