Which term describes the predominance of using the right hand among humans?

• A. Right Handedness
• B. Left Handedness
• C. Ambidexterity
• D. Mixed-Handedness

Answer: (A)

Handedness is the pattern of preferring one hand over the other for skilled tasks such as writing, throwing, or eating. When that preference is toward the right hand, the term used is right-handedness. This describes a predominance, meaning most actions are done with the right hand rather than the left.

Left-handedness would be the opposite pattern, where the left hand is favored. Ambidexterity means someone can use both hands with similar skill, without a strong, lasting preference for one. Mixed-handedness refers to inconsistent hand preference across different tasks, rather than a clear, dominant hand.

So, the best description for the predominance of using the right hand among humans is right-handedness.
