☀ discord surfaced

The sentence would read: "A note of discord during the leaders' meeting at the UN."

Explanation: "Discord" refers to a lack of agreement or harmony, which fits the context of a potentially tense situation arising during the meeting. The other options don't fit the context:

• Friction surfaced: "Friction" also refers to conflict or disagreement, but "discord" is a more appropriate word choice in this context.

• Grievance surfaced: "Grievance" refers to a complaint or resentment, but it might not convey the exact nuance of a lack of agreement during a meeting.

• Strife surfaced: "Strife" means conflict or struggle, but "discord" is a more common and suitable term for describing tension in a meeting.
