To find the difference $$ 3 \frac{1}{7} - \frac{2}{7} $$, we can follow these steps:

1. **Convert the mixed number to an improper fraction**:
   $$
   3 \frac{1}{7} = \frac{3 \times 7 + 1}{7} = \frac{21 + 1}{7} = \frac{22}{7}
   $$

2. **Subtract the fractions**:
   $$
   \frac{22}{7} - \frac{2}{7} = \frac{22 - 2}{7} = \frac{20}{7}
   $$

Now, let's check the options provided:

- a) $$ \frac{26}{14} $$
- b) $$ \frac{36}{7} $$
- c) $$ \frac{26}{7} $$
- d) $$ \frac{22}{7} $$

The result we calculated is $$ \frac{20}{7} $$, which is not listed among the options.

Let's double-check the calculations to ensure accuracy:

1. **Convert $$ 3 \frac{1}{7} $$ to an improper fraction**:
   $$
   3 \frac{1}{7} = \frac{22}{7}
   $$

2. **Perform the subtraction**:
   $$
   \frac{22}{7} - \frac{2}{7} = \frac{20}{7}
   $$

The calculations are correct, and the answer is indeed $$ \frac{20}{7} $$.

Since none of the options match $$ \frac{20}{7} $$, it appears there may be an error in the options provided.
The difference is $$ \frac{20}{7} $$, which is not among the given options.
