organic chemistry - Confusion on enantiomers and meso compounds

Question: Are these compounds enantiomers?

Attempt: The compounds given are mirror images. But if I rotated the three bonds in the third carbon (configuration will not change), I will get a meso compound (plane of symmetry) :

So are these compounds enantiomers or meso compounds?

Answer

You are right, the 2 structures are equivalent and the substance has a plane of symmetry and is a meso compound. When in doubt, make a 3D model if possible.
