Let's determine the block for each element provided:(A) Cd (Cadmium)Cadmium (atomic number 48) is located in Group 12, Period 5 of the periodic table.Its electron configuration is $[ Kr ] 4 d^{10} 5 s^2$.Elements in Groups 3 through 12, where the d-orbitals are being filled, are known as d-block elements. Cadmium fits this description.So, (A) Cd matches with (III) d-block.(B) Eu (Europium)Europium (atomic number 63) is a lanthanide element.Lanthanides and actinides are typically placed below the main body of the periodic table and comprise the $f$-block elements, where the f-orbitals are being filled.Its electron configuration is $[ Xe ] 4 f ^7 6 s^2$.So, (B) Eu matches with (I) f-block.(C) Se (Selenium)Selenium (atomic number 34) is located in Group 16, Period 4 of the periodic table.Its electron configuration is $[ Ar ] 3 d^{10} 4 s^2 4 p ^4$.Elements in Groups 13 through 18, where the p-orbitals are being filled, are known as p-block elements. Selenium fits this description.So, (C) Se matches with (IV) p-block.(D) Ba (Barium)Barium (atomic number 56) is located in Group 2, Period 6 of the periodic table.Its electron configuration is $[ Xe ] 6 s^2$.Elements in Group 1 (alkali metals) and Group 2 (alkaline earth metals), where the s-orbitals are being filled, are known as sblock elements. Barium fits this description.So, (D) Ba matches with (II) s-block.
