I am glad we all agreed that Bromine water is used to test for the presence of unsaturated hydrocarbons (Alkenes and Alkynes). However, take a close look at the options, the only option between the two unsaturated hydrocarbons is Alkene, which makes option A the correct answer.
N.B: I hope someone is not mistaking Alkyl for Alkyne? Please they are not the same thing. The answer would have been controversial if we had alkene and alkyne in the options.
I hope this further explains it.
Thank you

The answer is meant to be both alkene and alkylene but alkene decolourises faster

Alkyne is more unsaturated than alkane, it should be the ans, though both of them cwn declourise bromine water.
