What nail shape is likely to cause stress on the nail?

• A. Square
• B. Round
• C. Stiletto
• D. Oval

Answer: (C)

The stiletto nail shape is designed to be sharply pointed at the tip, resembling a stiletto heel. This shape tends to put additional stress on the nail because the narrow point increases the risk of breakage. The extreme point can make it more difficult for the nail to withstand everyday activities. Furthermore, the design requires that the nail be filed to a very thin edge, which can further compromise its strength. This shape is often favored for its dramatic aesthetic appeal in fashion settings, but the trade-off is that it demands careful maintenance and can be prone to damage.

In contrast, other shapes such as square, round, and oval distribute pressure more evenly across the nail surface and maintain a sturdier structure, which helps reduce the risk of stress and breaking.
