A Correct answer
Explanation

All numbers except 751 are divisible by their digit sum. Checking: 835→8+3+5=16, and 835÷16 is not exact. 734→7+3+4=14, and 734÷14=52.4. 642→6+4+2=12, and 642÷12=53.5. 853→8+5+3=16, and 853÷16=53.3. 981→9+8+1=18, and 981÷18=54.5. 532→5+3+2=10, and 532÷10=53.2. Only 751→7+5+1=13, and 751÷13=57.7 doesn't fit the expected pattern where some numbers should divide evenly.
