Solution

This is the correct option because it indicates that English is another subject taught in addition to Mathematics. 3. Option C: beside Beside means next to or by the side of. It does not fit the context of teaching subjects. 4. Option D: both Both is a pronoun indicating two things. However, it requires a conjunction like and to make the sentence grammatically correct (e.g., "Our sir teaches both Mathematics and English").

Therefore, the best option is B: besides, as it accurately conveys that the teacher teaches English in addition to Mathematics.
