Which statement best describes PascalCase usage?

• A. It uses underscores to separate words
• B. PascalCase, where the first letter of each word is capitalized
• C. All letters are lowercase
• D. It uses all uppercase letters

Answer: (B)

PascalCase uses capitalization to mark word boundaries without separators. Each word starts with an uppercase letter, and the words are written together as one identifier, with no underscores or spaces. For example, UserProfile or OrderTotal. This style is commonly used for class or type names in many languages, such as C# and Java. So the statement that describes PascalCase as capitalizing the first letter of each word fits perfectly. In contrast, using underscores to separate words corresponds to snake_case, all lowercase is simply a different convention not matching PascalCase, and all uppercase is typically used for constants in many languages.
