To find the sum of $$\frac{1}{9} + \frac{5}{12}$$, follow these steps:

1. **Find a Common Denominator:**
   - The denominators are 9 and 12.
   - The least common multiple (LCM) of 9 and 12 is 36.

2. **Convert Each Fraction to the Common Denominator:**
   - $$\frac{1}{9} = \frac{1 \times 4}{9 \times 4} = \frac{4}{36}$$
   - $$\frac{5}{12} = \frac{5 \times 3}{12 \times 3} = \frac{15}{36}$$

3. **Add the Converted Fractions:**
   $$
   \frac{4}{36} + \frac{15}{36} = \frac{4 + 15}{36} = \frac{19}{36}
   $$

**Therefore, the correct answer is:**

**a) $$\frac{19}{36}$$**
The sum is $$ \frac{19}{36} $$.
