Which of the following molecules represents the order of hybridisation $s{p}^2,s{p}^2,sp,sp$ from left to right atoms?

We need to determine the hybridization of each carbon:Carbon with all single bonds: $s{p}^3$ Carbon with one double bond: $s{p}^2$ Carbon with one triple bond or two double bonds: $sp$ Checking ${\text{CH}}_2=\text{CH}-\text{C}\equiv \text{CH}$:${\text{CH}}_2$: 1 double bond $\to s{p}^2$$\text{CH}$: 1 double bond $\to s{p}^2$$\text{C}$: 1 triple bond $\to sp$$\text{CH}$: 1 triple bond $\to sp$ Order: $s{p}^2,s{p}^2,sp,sp$.
