The strength of an acid is based or measured on the no.of hydrogen ion released upon hydrolysis.

Yes it depends upon no of protons released; I agree with @Ekeleme.

Strength of an acid is referred as ability to release protons but the strength of an acid depends on (or determined by) its electronegativity.

So true! @Ambiha.

Let me explain with an example HCl is more acidic than HCO3. Meaning it has higher strength!

Cl has higher electronegative than Br, but HCL is weaker acid than HBr.

It depends on electronegativity and the size of the atom covalently bonded to the hydrogen atom. Induction and resonance also play roles.

Depends on the protons released not Electronegativity.

The question says, "number of protons released. "

It does not say how easy it is to release those protons. An acid increases in strength based on how easy it is to release hydrogen atoms.

H3PO4 has the potential to release 3 hydrogens, as opposed to HCl, with only one potential hydrogen release, however, HCl releases hydrogens more easily.

Acidic quality fully depends on the release of a proton. But electronegativity right.

The Strength of acid depends on electronegativity. Strong acid easily dissociates in solution. They have an ability to lose proton while weak acid partially dissociates.
