Which one is the correct order of acidity?

Acidity increases with increasing $s$ -character of the hybridized carbon atom ($sp>s{p}^2>s{p}^3$).Alkynes ($sp$, 50% $s$) are more acidic than alkenes ($s{p}^2$, 33.3% $s$), which are more acidic than alkanes ($s{p}^3$, 25% $s$).Among alkynes, terminal alkynes with more acidic hydrogens are more acidic. $\text{CH}\equiv \text{CH}$ has two such hydrogens, while ${\text{CH}}_3-\text{C}\equiv \text{CH}$ has one and an electron-donating methyl group which slightly decreases acidity.Order: $\text{CH}\equiv \text{CH}>{\text{CH}}_3-\text{C}\equiv \text{CH}>{\text{CH}}_2={\text{CH}}_2>{\text{CH}}_3-{\text{CH}}_3$.
