Final answer:
The opposite of abandon is 'restraint' because while abandon means to leave or give up, restraint involves control and holding on.
Step-by-step explanation:
The word abandon typically means to leave something behind or to give something up. When we are choosing an antonym for abandon, we need to consider a word that means the opposite, which is to hold onto something or to continue being in a place. Therefore, the opposite of abandon is option (d) restraint, which implies control and holding onto something or someone. The choices (a) arrival and (b) presence are possibly confusing because they indicate being at a location, which is somewhat opposite to leaving, but they are not actions that directly oppose the act of abandonment. Choice (c) security is a feeling or state of being free from danger or threat, which does not directly relate to the action of abandoning or holding onto something. In summary, when one exercises restraint, they are, in essence, not abandoning something, therefore making it the best antonym in this context.
