To solve the problem, we need to simplify the expression \(\sqrt[3]{40x^6y^5}\).

### Step 1: Break Down the Radicand
The radicand is \(40x^6y^5\). Let's break this into smaller parts:

\[
40x^6y^5 = 8 \times 5 \times x^6 \times y^3 \times y^2
\]

Here, \(8\) is a perfect cube (\(8 = 2^3\)), and \(x^6\) can be written as \((x^2)^3\).

### Step 2: Apply the Cube Root
Now apply the cube root to each part:

\[
\sqrt[3]{8 \times 5 \times x^6 \times y^5} = \sqrt[3]{8} \times \sqrt[3]{5} \times \sqrt[3]{x^6} \times \sqrt[3]{y^5}
\]

Simplify each part:

- \(\sqrt[3]{8} = 2\)
- \(\sqrt[3]{x^6} = x^2\)
- \(\sqrt[3]{y^5} = y \times \sqrt[3]{y^2}\)

So the expression simplifies to:

\[
2x^2y \sqrt[3]{5y^2}
\]

### Step 3: Match with the Given Options
Looking at the options provided:

- The second option matches exactly: \( \boxed{2x^2y \sqrt[3]{5y^2}} \).

Thus, the correct answer is the second option.
