Verified step by step guidance

Step 1: Understand the ABCD rule, which is a guideline used to identify malignant melanoma. The rule stands for Asymmetry, Border irregularity, Color variation, and Diameter greater than 6mm.

Step 2: Review the characteristics of malignant melanoma. It is a type of skin cancer that often presents with irregular shapes, uneven borders, multiple colors, and a size larger than 6mm.

Step 3: Compare the ABCD rule to the other skin disorders listed in the problem. Eczema, impetigo, and psoriasis do not typically exhibit the features described by the ABCD rule.

Step 4: Recognize that malignant melanoma is the correct answer because it aligns with the diagnostic criteria outlined in the ABCD rule.

Step 5: Conclude that the ABCD rule is specifically designed to help identify malignant melanoma, distinguishing it from other skin disorders.
