To solve this, we need to find the derivative of the given function:

\[
t(x) = \ln(4x^3 + 4x^2 + 6x + 4)
\]

### Step-by-step solution:

#### 1. Use the chain rule:
The derivative of \( \ln(f(x)) \) is:

\[
\frac{d}{dx}[\ln(f(x))] = \frac{f'(x)}{f(x)}
\]

Here, \( f(x) = 4x^3 + 4x^2 + 6x + 4 \).

#### 2. Find \( f'(x) \):
Now we compute the derivative of \( f(x) \).

\[
f'(x) = \frac{d}{dx} \left( 4x^3 + 4x^2 + 6x + 4 \right)
\]
Using power rule:
\[
f'(x) = 12x^2 + 8x + 6
\]

#### 3. Apply the chain rule:
Now apply the chain rule to get the derivative of \( t(x) \):

\[
t'(x) = \frac{f'(x)}{f(x)} = \frac{12x^2 + 8x + 6}{4x^3 + 4x^2 + 6x + 4}
\]

Thus, the first derivative of \( t(x) \) is:

\[
t'(x) = \frac{12x^2 + 8x + 6}{4x^3 + 4x^2 + 6x + 4}
\]

#### Correct Answer:
The correct answer matches the second option from the choices provided:

\[
\boxed{\frac{12x^2 + 8x + 6}{4x^3 + 4x^2 + 6x + 4}}
\]
