A frameshift mutation occurs when bases are deleted or inserted in such a way that it alters the reading frame of the DNA sequence. In this case, you need to find a sequence that results from a deletion of one or more nucleotides.

Let's analyze the provided options:

1. **ATG AAG TTG GCT AA** - This seems to have deleted one base pair (the "T" from "TTT"), which shifts the reading frame.

2. **ATG TTT GGC TAA** - This maintains the same reading frame, as it appears to have deleted "AAG" entirely, but the sequence isn't an exact frame shift.

3. **ATG UAA GTT TGG CTA A** - This option includes "U," which is not a valid base in DNA, ruling it out.

4. **ATG AAG TTT GGC GCA TAA** - This includes an extra "GCA," which results in an insertion, rather than a deletion.

The correct choice that represents a frameshift mutation due to deletion is:

**ATG AAG TTG GCT AA**.
