The correct answer is: B. too
The sentence “Farida sings very well and Salim too” means that Salim also sings very well. The word “too” is used to add information to a sentence, and in this case it is used to add the information that Salim sings very well.
The other options are not correct because they do not add the same information to the sentence. The word “even” is used to add emphasis, and in this case it would not make sense to emphasize that Salim sings very well. The word “also” is used to add information to a sentence, but in this case it would not make sense to add the information that Salim sings very well. The word “so” is used to introduce a conclusion, and in this case it would not make sense to conclude that Salim sings very well.
Here are some examples of how the word “too” can be used in a sentence:
- I like ice cream, and my friend likes it too.
- I’m going to the store, and I’ll pick up some milk too.
- I’m tired, and I think you’re tired too.
