问题如下：
Assume
that the DM country has what is considered a low-yield safe haven currency
while the EM country has a high-yield currency whose value is more exposed to
fluctuations in the global economic growth rate. An increase in safe haven
demand would most likely:
选项：
A.increase the risk premium demanded by international
investors to hold assets denominated in the EM currency
raise the return earned on carry trade strategies
exert upward pressure on the value of the EM currency
解释：
During
times of intense risk aversion, investors will crowd into the safe haven
currency. This tendency implies an increased risk premium demanded by investors
to hold the EM currency.
解析：在风险厌恶上升的时期，投资者会涌向避险货币。这一趋势意味着，投资者持有新兴市场货币所需的风险溢价上升。因此只有A正确。
请问这个题目和FX carry trade有什么关系？
FX carry trade是去高收益的国家投资，所以就是从DM借钱，去EM投资,
然后EM风险高了，所以EM就需要raise risk premium来留住投资者, 所以B选项是对的呀，raise return strategy?
