The phrase "Every cloud has a silver lining" is a popular idiom that conveys a message of optimism, suggesting that even in difficult or challenging situations, there is always a positive aspect or potential for hope. The term "silver lining" specifically refers to the bright outlines that appear around clouds when sunlight shines through them. This imagery evokes the idea that despite the ominous or gloomy appearance of clouds, a glimmer of light represents hope or positive outcomes.

In contrast, the other options do not fit the established expression: "golden lining" is less common and doesn't have the same recognized meaning; "bright" lining does not convey the idea of hope or positivity specifically associated with adversity; and "positive" lining, while conveying a good sentiment, lacks the figurative or poetic quality inherent in the idiom.

Thus, "silver" is the most appropriate and widely recognized word to complete the sentence, highlighting the concept that challenges often come with hidden benefits or lessons. This idiom serves as a reminder to seek the good or valuable aspects even when faced with hardships.
