  1. 8

  2. 9

  3. 1

  4. 0
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This is a cryptarithm where ABCD is a 4-digit number and D is a single digit. The product DCBA must also be a 4-digit number. Testing D=9: 1089 × 9 = 9801, which satisfies the pattern (DCBA where D=9). Testing other values shows that only D=9 produces a valid reversal pattern.
