D. 401

Answer

To solve the question "What should be subtracted from the product 102 × 201 to get 19999?", we can follow these steps:

### Step 1: Calculate the product of 102 and 201.
First, we need to find the product of 102 and 201.

\[ 102 \times 201 = 20502 \]

### Step 2: Set up the equation.
Let \( x \) be the number that needs to be subtracted from the product. According to the problem, we can set up the equation:

\[ 20502 - x = 19999 \]

### Step 3: Solve for \( x \).
To find \( x \), we can rearrange the equation:

\[ x = 20502 - 19999 \]

Now, we perform the subtraction:

\[ x = 20502 - 19999 = 503 \]

### Conclusion
Thus, the number that should be subtracted from the product 102 × 201 to get 19999 is:

\[ \boxed{503} \]
