Molecules with a plane of symmetry between the chiral centers are achiral and meso. From the given molecules (Picture attached) only (A) compound 1 is meso.
When compounds possess a plane of symmetry between the chiral centers they are called achiral or meso compounds. Among the given compounds (A) compound 1 have a plane of symmetry. So we can say compound one is a meso or achiral compound. Compounds two, three, and four have no plane of symmetry, as you can see in the structures attached. So all other compounds (compound 2, compound 3, and compound 4) except compound one are not meso or achiral.
You can also learn about meso compounds from the following question:
Iron, or Fe, has 26 electrons, with two electrons in the outer valence shell. Iron is a transition metal and is both lustrous and easy to work with. Iron is also prone to rust, especially in damp environments. Iron is a ferrous metal, meaning that it can be magnetized.
