Uneven growth due to illness or injuries is the most likely cause of corrugations in nails because this factor can directly affect the formation and growth of the nails. However, the other options, dry cuticle, exposure to strong chemicals, and nutrition deficiency, may also contribute to the appearance of corrugations. Dry cuticle may cause the nail to detach from the nail bed, which can result in an uneven surface. Exposure to strong chemicals can weaken the nail structure and lead to abnormal growth or changes in texture. Finally, nutrition deficiency can impact the strength and growth of the nail, potentially causing ridges or grooves. While these factors may not be the primary cause of corrugations, they can contribute to the appearance of this condition.
