A Correct answer
Explanation

Data aligned on its natural boundary (fullword for 4-byte data) executes faster because the CPU can fetch it in a single memory cycle. Misaligned data may require multiple memory accesses, slowing execution. Halfword alignment is for 2-byte data; doubleword is for 8-byte data. Fullword boundary is optimal for typical 4-byte word operations.
