The definition of 'mitigate' is to make something milder or to moderate its severity. This term is often used in contexts where there is a need to reduce the negative impact of something. For example, when discussing environmental issues, one might seek to mitigate the effects of climate change by implementing policies that reduce greenhouse gas emissions.

In contrast, the other choices present definitions that do not align with the meaning of 'mitigate.' Worsening a situation, severing ties, or avoiding conflict all involve actions that either escalate issues or create distance between entities, rather than easing or moderating them. Thus, making something milder or moderating its severity is the most accurate interpretation of 'mitigate.'
