Lower Tool Bar

I had 2 top tool bars.  At the end of the lower one there was an option to close which I did. Now I can't re-open it again.  How do I do this.  I have Adobe Acrobat Reader DC (32-bit) on my windows 10 pc 64-bit. All versions are up-to-date.  The bottom attachment is the one I want.  The lower tool bar begins with "Comment" and ends with "Close.  I closed it but now I can't see how to reopen it.

Help Please, Wendy

  How do I open this so it looks like
