d..Al2+ ---Al3+
because Bond breaking is endothermic process and Bond making is exothermic process
in 1st option intitally you are putting an extra electron in sulphur Orbit which is a bond making process and further you are putting next electron in its Orbit which is also of Bond making process which is exothermic in nature
in Na+ + Cl- it is also about making process so it is exothermic
in 3rd you are putting an extra electron in nitrogen sorbate hence it is Bond making process and exothermic
but in Forth there are initially two less electrons in aluminum orbit (2+) and after u take one more electron out which is a bond breaking process and hence it is endothermic
