Port de bras and Grade 1 example describes:

• A. The carriage of the arms; example: moving from 5th en haut to 2nd with a smooth arc.
• B. The turning of the hips to align the spine.
• C. The position of the feet when landing from a jump.
• D. The alignment of the head with the spine.

Answer: (A)

Port de bras is about how the arms are carried and moved through positions with a smooth, controlled arc, while keeping the shoulders down and the upper body steady. In Grade 1, a classic example is shaping the arms by moving them in a graceful arc from one position to another, such as from fifth en haut to second, rather than any hip, head, or foot actions.

This option best shows the essence of port de bras: the carriage and movement of the arms themselves, emphasizing the line, length, and fluidity of the arm path. The other ideas focus on different aspects—hip turning, foot placement on landing, or head alignment—which are important in dance but pertain to other elements (alignment or footwork) rather than the arm carriage itself.
