Answer:
is formed and it has three unpaired electrons.
Explanation:
Blue 
reacts with water to produce pink colored complex.
In this complex, 
ion forms an octahedral complex with six 
ligands.
As is a weak field ligand therefore ion remains in low spin state.
Hence electronic configuration of ion in this octahedral geometry is 
with total three unpaired electrons.
The correct answer is A. Analgesic are used to treat all forms of pain and because of their wide availability people buy them without proscription. This leads to a lot of undesirable side effects.
