INFORMATION ABOUT POSSIBLE EXCURSION TO MANALI BY DELHI PUBLIC SCHOOL STUDENTS.
Good day sir. My name is Suresh Bachan, Secretary of Students Council of Delhi Public School, New Delhi and I want to make enquiries about the feasibility of embarking on an excursion with the students of the aforementioned school.
We want to come and enjoy the ambience and rich culture of Manali and in doing so, expand our knowledge and horizon about culture, arts and crafts and other indigenous things.
Please treat this request with the kindest consideration.
Yours faithfully,
Suresh Bachan.
You didn't italize or mark the phrase, but I see one good candidate:
"The circus animal trainer" is in a way another name given to Mervin, a kind of "renaming" him: this is called an appositive phrase, so if this was the phrase appositive phrase is the answer! (also, I don't see the other phrases here).
