why might a country choose to devalue its currency?\n to please its trading partners\n to encourage…

Brief Explanations:

When a country devalues its currency, foreign - currency can buy more of its goods and services. This makes its exports cheaper for foreign buyers, thus encouraging exports. Devaluing is not mainly to please trading partners, it discourages imports as domestic consumers need more of the devalued currency to buy foreign goods, and it has no direct relation to reducing taxes.

Answer:

to encourage exports
