A Correct answer
Explanation

Treat the two P's as one unit. The letters are H, A, (PP), Y. There are 4! = 24 arrangements.

AI explanation

Treat the two P's as a single combined letter, which reduces the word HAPPY to four distinct units (H, A, PP, Y). The number of arrangements for these 4 units is calculated using the factorial method as 4 factorial. 4 factorial equals 24, which is the total number of possible arrangements.
