English Idiom — Identify the meaning. Sentence: I have a bone to pick with you in this matter.

Introduction / Context:
The idiom “to have a bone to pick with someone” means to have a grievance to discuss, often because one is annoyed or angry about something the other person did. It signals impending confrontation or at least a firm conversation about a complaint. This is a staple expression in everyday English and appears in novels, workplace talk, and emails.

Given Data / Assumptions:

• Speaker addresses “you,” indicating a direct interpersonal issue.
• Phrase: “in this matter,” implying a specific grievance.
• We choose the option that captures the emotional stance behind the phrase.

Concept / Approach:
While the idiom emphasizes a grievance to discuss, the emotional driver is annoyance or anger. Among the options, “Am angry” conveys this emotional state most clearly. The other choices suggest agreement, indebtedness, or cooperation—all of which contradict the idiom’s confrontational undertone.

Step-by-Step Solution:

Verification / Alternative check:
Paraphrase: “I am angry with you about this matter and wish to discuss it.” This keeps both the affect and the intent to address the issue.

Why Other Options Are Wrong:

• Am in agreement: Opposite of confrontation.
• Am indebted: Expresses gratitude, not grievance.
• Will join hands: Cooperation; not conflict.

Common Pitfalls:
Interpreting the idiom as merely “to discuss.” Although discussion may follow, the phrase specifically signals a complaint rooted in anger or irritation.

Final Answer:
Am angry
