Which phrase from the sentence gives it a formal tone? with great sorrow and many fond memories, i must leave this important phase of my life and move on to more challenges and new faces. i must leave move on to more challenges

The correct answer is "With great sorrow and many fond memories"

Explanation:

The noun "sorrow" gives the phrase a formal tone because it is usually used in more ceremonial or polite situations and is not as common as the word "sadness".

At the same time, the adjective "fond" is more solemn than many of its synonyms, like "nice" or "dear", thus elevating the tone of the sentence.
