Let's simplify the expression step-by-step:

The expression is:

\[ 4(5m + 3) + 2m \]

First, distribute the \(4\) into the parentheses:

\[ 4 \cdot 5m + 4 \cdot 3 + 2m \]

This simplifies to:

\[ 20m + 12 + 2m \]

Next, combine the like terms (\(20m\) and \(2m\)):

\[ 20m + 2m = 22m \]

Thus, the expression simplifies to:

\[ 22m + 12 \]

Now, let's compare this with the provided choices:

A) \( 20m + 6 + 2m \)

B) \( 22m + 6 \)

C) \( 20m + 12 + 2m \)

D) \( 22m + 12 \)

The most simplified expression matching our result is:

**D) \( 22m + 12 \)**
