A Correct answer
Explanation

The F$FAO function (Formatted ASCII Output) uses format codes to construct strings. The format "!UL!3ZL!3AS" means: !UL = unsigned long (2), !3ZL = 3-digit zero-filled long (003), !3AS = 3-character string from "HELLO" (HEL). When combined: 2 + 003 + HEL = 2003HEL, which matches option A.
