Let's solve the problem step by step.

We are given:

\[
[6(xy + 3) - 4xy] - 4(xy + 3)
\]

### Step 1: Distribute the terms inside the brackets.
1. \( 6(xy + 3) \) becomes:
   \[
   6xy + 18
   \]
   
2. \( -4(xy + 3) \) becomes:
   \[
   -4xy - 12
   \]

Now, rewrite the expression:

\[
(6xy + 18 - 4xy) - (4xy + 12)
\]

### Step 2: Combine like terms.
- \( 6xy - 4xy = 2xy \)
- \( 18 - 12 = 6 \)

Thus, the simplified expression is:

\[
2xy + 6
\]

### Answer:
The correct choice is **D. 2xy + 6**.
