What does the term 'justifiably' mean?

The term 'justifiably' means to do something 'with good reason'. This implies that an action, decision, or belief is supported by evidence, logic, or moral grounds. When something is described as justifiable, it indicates that there are valid reasons or justifications behind it, making it acceptable or permissible within a specific context. In contrast, the other choices suggest a lack of reasoning or care, which does not align with the concept of justifiability. For example, acting unreasonably, carelessly, or irresponsibly reflects actions taken without sufficient reasoning, which directly opposes the meaning of 'justifiably'.
