Correct Answer: Political instability

Solution : The correct answer is c) Political instability

Political instability, such as changes in government, civil unrest, or geopolitical tensions, can lead to a loss of confidence in a country's economy and its currency. Investors may perceive political instability as a risk and seek to sell off the country's currency, leading to its depreciation.

It's important to note that currency exchange rates are influenced by a variety of factors, including economic fundamentals, monetary policy, market sentiment, and global economic conditions. The interplay of these factors can result in currency appreciation or depreciation.
