Which function converts the entire string to proper case (first letter of each word uppercase)?

• A. InitCap
• B. Upper
• C. Lower
• D. Substring

Answer: (A)

Achieving proper case means capitalizing the first letter of each word while usually leaving the rest of the letters in lowercase. This is exactly what InitCap does: it scans each word, makes the initial character uppercase, and typically converts the remaining characters to lowercase. So an input like "hello WORLD from DBA" becomes "Hello World From Dba." This differs from converting the whole string to uppercase (Upper) or to lowercase (Lower), which affect every character without respecting word boundaries. Substring is for extracting a portion of the string and doesn't alter case. Therefore, InitCap is the correct choice for turning the entire string into proper case.
