Which statement about PascalCase usage is true?

Which statement about PascalCase usage is true?

• A. It uses underscores to separate words
• B. It uses all lowercase letters
• C. It uses camelCase for column names
• D. It uses PascalCase, capitalizing the first letter of each word

Answer: (D)

PascalCase is a naming style where words are joined together without spaces and every word starts with a capital letter. This means you see identifiers like CustomerOrderDetail or EmployeeSalaryHistory, with no underscores or spaces and with the first letter of each word capitalized. The statement is true because it directly describes this rule. Using underscores would be snake_case, not PascalCase. All lowercase letters would be a different style and wouldn’t show the word boundaries with capitals. Starting with a lowercase letter and capitalizing subsequent words describes camelCase, which is distinct from PascalCase.
