Answer: C, D

Explanation:

The commands that should be added to /etc/bash_profile to change the language of messages from an internationalised program to Portuguese (pt) are: export LANG=“pt”

export LC_MESSAGES=“pt”

The LANG and LC_MESSAGES environment variables are used to control the language of messages

from an internationalised program. The LANG variable sets the default locale for all categories, such

as collation, currency, date and time formats, etc. The LC_MESSAGES variable sets the locale for the

language of messages, overriding the LANG variable for this category. Therefore, to change the

language of messages to Portuguese, both variables should be set to “pt” in /etc/bash_profile, which

is a script that is executed when a user logs in. This will affect the current user and any subsequent

login sessions.
