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

At $300\, K$ and $1\, atm,\, 15\, mL$ of a gaseous hydrocarbon requires $375\, mL$ air containing $20\%\,\, O_2$ by volume for complete combustion. After combustion the gases occupy $330\, mL.$ Assuming that the water formed is in liquid form and the volumes were measured at the same temperature and pressure, the formula of the hydrocarbon is :
