4. (10 points) Please fill in each box in the figure with the appropriate number, so that the multiplication vertical format holds. Then the product is (
A. 2986
B. 2858
C. 2672
D. 2754
【Analysis】Starting from special cases, if there is a carry in the result's digit 2, then the digit above 0 can only be 9. According to 910 divided by 7 yielding 130, the digit before 7 can only be 1, which contradicts the digit 0. Therefore, there is no carry. Based on the known digits, the analysis without contradiction is consistent with the problem.

【Solution】First, according to the leading digit of the result being 2, if there is a carry, then the digit above 0 can only be 9. According to 910 divided by 7 yielding 130, the digit before 7 can only be 1, which contradicts the digit 0. Therefore, the leading digit of the three-digit multiplier can only be 1 or 2. Since the multiplier contains 7 and the result is a three-digit number, the leading digit of the three-digit multiplier can only be 1.

Thus, the digit before 7 can only be 2. Based on the known digit 0, the tens place of the three-digit multiplier is 0. According to the digit 7 in the multiplier and the three-digit number, there is a carry of 1, so the units digit can only be 2.

Therefore, it is $102 \times 27=2754$.
Hence, the answer is: $D$.
