Thin nails are particularly susceptible to breaks and splitting due to their structure and composition. Unlike thicker nails, which have more keratin and tend to be more resilient, thin nails lack the necessary strength to withstand everyday stress and pressure. This fragility can be exacerbated by factors such as environmental conditions, improper nail care, and exposure to harsh chemicals. Therefore, they are more likely to experience chipping, cracking, and splitting because they do not have the robust characteristics that provide durability.

In contrast, curved nails often have a different shape and growth pattern that can sometimes provide natural strength. Thick nails generally offer more protection and resilience against breaking, while healthy nails, regardless of thickness, tend to be strong and well-maintained. Instead of being prone to damage, healthy nails typically indicate adequate care and are less likely to break or split. Thus, thin nails are the most vulnerable, making them the correct choice in this question.
