House plant newbie question

Hi all, first post so please be gentle!

We (wife and I) are very new to the gardening world and at the moment only have a few house plants as a way of dipping our toe in.
We have this plant (see pic) in our living room which we repotted before Christmas.
Initially the disruption of repotting the plant didn’t go down to well and quite a few of the leaves began to fall off. Over time however the plant grew stronger and seems to be doing well now.
One of the three “trunks” (?!? Can you tell I’m not a gardener haha!) has no leaves on it at all and appears to be dead. The other two are doing well and some even have some new leaves forming.
My question is, do I remove the dead “trunk” or will it be fine staying there?

Thanks everyone.

Difficult to actually see the dead one form the pictures.
If you are sure its dead you can cut it back to live wood.

 

Thanks. Is there a way to tell if it is dead? There are no leaves on it at all

 

I'd cut it back a bit at a time, if it's dead it will be brown inside.
Keep cutting down the stem until you find a live bit.

 

Thank you sir

 

You're welcome.
