You must show your attempt before we can help you.  However, there may be an assumption baked into the question that is worth exploring at some point.

I don't know what do you mean. but if you had to guess what would you choose ?

[Babcock_Hall]

I am not suggesting that you guess.  According to the Forum Rules (see red link above) you must show your attempt or provide your thoughts before we can help you.  Here are two suggestions for how you can get started.  One is to write a balanced equation.  Two is to look for what chemical property or properties distinguish the four choices.  As for my second sentence above, it can wait until the end.

I don't know where to start. i don't know the idea of this question i tried.

How do you think sodium metal will react?  In other words, what do you think will happen?

It will replace the H in the compound.

I know that the bond between the H and the The O in phenol is weak.

Is it C6H5COOH because its more acidic than the other compunds ?

[Babcock_Hall]

Given an assumption about the identity of the product, I would agree that it is easier to remove H from a phenol than an alcohol where the oxygen is bonded to a carbon with sp³-hybridization, an aliphatic alcohol.  Is there a property that you can think of that describes this?  A number related to acidity?

Looks like the question asks which of these compounds is the strongest acid.

@OP, How do we classify acids by acid strength?  In other words, what number do we use?
