D. 6745

Explanation

To solve the expression \( 4900 \div 28 \times 444 \div 12 \), we will follow the order of operations and simplify step by step.

### Step 1: Simplify \( 4900 \div 28 \)

First, we divide \( 4900 \) by \( 28 \).

\[ 4900 \div 28 = 175 \]

### Step 2: Simplify \( 444 \div 12 \)

Next, we divide \( 444 \) by \( 12 \).

\[ 444 \div 12 = 37 \]

### Step 3: Multiply the results from Step 1 and Step 2

Now, we multiply the results from the previous steps:

\[ 175 \times 37 \]

To calculate this, we can break it down:

\[ 175 \times 37 = 175 \times (30 + 7) = 175 \times 30 + 175 \times 7 \]

Calculating each part:

\[ 175 \times 30 = 5250 \]
\[ 175 \times 7 = 1225 \]

Now, add these two results together:

\[ 5250 + 1225 = 6475 \]

### Final Result

Thus, the final answer is:

\[ \boxed{6475} \]
