What is the definition of "boon"?

The term "boon" refers to something that is beneficial or advantageous, providing positive outcomes or relief. It is often used to describe a situation, event, or thing that brings joy, help, or a significant improvement to a person's life. The concept of a boon conveys the idea of a blessing or a positive benefit, which aligns perfectly with the correct choice. In various contexts, a boon could mean a fortunate circumstance or a helpful gift. For example, a technological advancement that simplifies tasks can be considered a boon to productivity.

The other choices reflect negative scenarios: a burden that creates distress, an undesirable outcome, and an exceptionally challenging task all convey themes of difficulty, challenge, or negativity, which do not align with the fundamentally positive connotation of the word "boon."
