It's B, because a negative charged Ion is an anion. And since it's 1- ,one valence electron is been added to H. So it has 2 valence electrons.
The characteristics of a chemical reaction are:
The lower energy of reactants → Transition state → High energy of products.

An atom is the simplest particle that exists and retains the property of the element. A compound is made up of two or more elements chemically combined.
AlPO4----> Al+3 + PO4-3
Ksp= [Al+3] x [PO4-3]= 9.84 x 10^-21
Ksp= (x) (x)= x^2
X^2= 9.84x10-21
x= 9.92 x 10^-11
The molar solubility is 9.92 x 10^-11
