please explain choices thourougly and stepwise

The structure of molecule is labeled as shown. Although hydrogen atoms are not specifically labeled, they are defined by the attachment to oxygen or carbon. For example, hydrogen on O1 is defined as H1, hydrogen on C2 as H2, and etc. With this in mind, propose the cleavage pathway leading to the peak 56(m/e) by assigning the locations where the bond is to break and where the bond is formed. One of the cleavage pathways involves the breaking up bond and transferring as well as breaking up and bonds. As a result, the formed fragment displayed on MS at 56(m/e) contains the following carbons: , which is a The lost species includes the following carbons: which is a and has mass of as well as which consists of The structure of molecule is labeled as shown.
