2. Right answer: Alegre
If your team scored a goal you must be happy, full of joy. This emotion in spanish is called alegría (happiness).
In this context you would not be agitado (troubled), enojado (angry) or furioso (furious).
When you are happy you say “estoy alegre”
Therefore the right option is B:
Alegre
3. Right answer: Por la última vez
For the last time is an expression that may be used if someone gives an ultimatum (normally when is followed by the exclamation sign) or to refer about the last occasion something happened.
The Spanish word vez (time, occasion) is feminine, hence the word last in spanish must be written in feminine, as well (última).
In addition, the defined article for a singular feminine noun la must preceed these words.
Therefore the right option is:
Por la última vez
