**Answer:**

The correct answer is option 2: **next Pinocogen=Uup**.

Let's analyze each option in detail to understand why option 2 is not the correct match:

1. **Next inert gas=Uuo**: This statement is correct. The noble gases are located in the last column (group 18) of the periodic table. As of now, the last discovered noble gas is Ununoctium (Uuo) with atomic number 118. Therefore, the next inert gas after Uuo would be the next element in the periodic table, which is currently not known.

2. **Next Pinocogen=Uup**: This statement is incorrect. Pinocogens are a hypothetical class of elements that may exist beyond the noble gases. However, as of now, no elements belonging to this class have been discovered or assigned atomic numbers. Therefore, Uup cannot be considered as the next Pinocogen.

3. **Next alkaline earth metal=Ubn**: This statement is correct. Alkaline earth metals are located in group 2 of the periodic table. The last discovered element in this group is Unbinilium (Ubn) with atomic number 120. Therefore, Ubn can be considered as the next alkaline earth metal.

4. **Last d block metal=Uut**: This statement is correct. The d-block metals are transition metals located in the middle of the periodic table. The last discovered element in this block is Ununtrium (Uut) with atomic number 113. Therefore, Uut can be considered as the last d-block metal.

In summary, the incorrect match is option 2: **next Pinocogen=Uup** because Pinocogens are hypothetical elements that have not been discovered or assigned atomic numbers yet.

1) Last inert gas element = Uuo (atomic number --> 118)
2) Pinocogen elements which is also called nitrogen family , so , last Pinocogen element = Uup (atomic number ---> 115)
3) Last alkaline earth metal = Ra (atomic number --> 88)
4) Last d block metal = Uub (atomic number --> 112)

So, correct answer is option 3 and 4
