Let's solve this problem step by step:

1. Let $ x $ be the number of bottles of paint.
2. She buys $ x $ bottles of paint for $1.29 each.
3. She buys 8 more canvases than bottles of paint, so the number of canvases is $ x + 8 $.
4. Each canvas costs $1.89.
5. The total pretax cost is $37.38.

### Set up the equation for the total cost:
The cost of the paint is $ 1.29x $, and the cost of the canvases is $ 1.89(x + 8) $.

So, the total cost equation is:
\[
1.29x + 1.89(x + 8) = 37.38
\]

### Expand and simplify:
\[
1.29x + 1.89(x + 8) = 37.38
\]
\[
1.29x + 1.89x + 15.12 = 37.38
\]
Combine like terms:
\[
3.18x + 15.12 = 37.38
\]

### Solve for $ x $:
\[
3.18x = 37.38 - 15.12
\]
\[
3.18x = 22.26
\]
\[
x = \frac{22.26}{3.18}
\]
\[
x \approx 7
\]

So, she buys 7 bottles of paint. 

### Number of canvases:
\[
x + 8 = 7 + 8 = 15
\]

### Answer:
She is buying 7 bottles of paint and 15 canvases, which corresponds to option **A**.
