Let's analyze the given information and solve for the required trigonometric functions step by step.

### Given:
$$
\cos \theta = \frac{3\sqrt{73}}{73}
$$

### 1. Finding $$\tan \theta$$

We know that:
$$
\tan \theta = \frac{\sin \theta}{\cos \theta}
$$

First, we need to find $$\sin \theta$$. Using the Pythagorean identity:
$$
\sin^2 \theta + \cos^2 \theta = 1
$$
$$
\sin^2 \theta = 1 - \cos^2 \theta
$$
$$
\cos^2 \theta = \left(\frac{3\sqrt{73}}{73}\right)^2 = \frac{9 \times 73}{73^2} = \frac{9}{73}
$$
$$
\sin^2 \theta = 1 - \frac{9}{73} = \frac{64}{73}
$$
$$
\sin \theta = \frac{8}{\sqrt{73}} = \frac{8\sqrt{73}}{73}
$$

Now, calculate $$\tan \theta$$:
$$
\tan \theta = \frac{\sin \theta}{\cos \theta} = \frac{\frac{8\sqrt{73}}{73}}{\frac{3\sqrt{73}}{73}} = \frac{8}{3}
$$

**Answer for $$\tan \theta$$:**
$$
\boxed{\tan \theta = \frac{8}{3}}
$$

### 2. Finding $$\sec \theta$$

$$\sec \theta$$ is the reciprocal of $$\cos \theta$$:
$$
\sec \theta = \frac{1}{\cos \theta} = \frac{73}{3\sqrt{73}} = \frac{73}{3\sqrt{73}} \times \frac{\sqrt{73}}{\sqrt{73}} = \frac{73\sqrt{73}}{3 \times 73} = \frac{\sqrt{73}}{3}
$$

**Answer for $$\sec \theta$$:**
$$
\boxed{\sec \theta = \frac{\sqrt{73}}{3}}
$$

### Summary of Choices:
- **A.** $$ \tan \theta = \frac{8}{3} $$ **✓ Correct**
- **B.** The function is undefined. **✗ Incorrect**

- **A.** $$ \sec \theta = \frac{\sqrt{73}}{3} $$ **✓ Correct**
- **B.** The function is undefined. **✗ Incorrect**

If you have any further questions or need additional clarifications, feel free to ask!
$$ \tan \theta = \frac{8}{3}, \quad \sec \theta = \frac{\sqrt{73}}{3} $$
