I don't agree with 2.
Here is how I did the one for C.
6C = 1s2 2s2 2p2 The two p electrons are unpaired.
8O = 1s2 2s2 2p4. The 2p can hold 6 electrons. We fill the 3 orbitals with electrons and the fourth one must pair; therefore, that leavs two unpaired electrons.
Now you do Ti and Si the same way.
