# Assessment 3

#### Which validation pattern correctly enforces "data must be between 4 and 8 bytes"?

* [x] OP\_SIZE OP\_4 OP\_GREATERTHANOREQUAL OP\_SIZE OP\_8 OP\_LESSTHANOREQUAL OP\_BOOLAND
* [ ] OP\_SIZE OP\_4 OP\_8 OP\_WITHIN
* [ ] OP\_SIZE OP\_4 OP\_EQUAL OP\_SIZE OP\_8 OP\_EQUAL OP\_BOOLOR
* [ ] OP\_DEPTH OP\_4 OP\_8 OP\_WITHIN

\
**Notes to Learners**

You need to check both the lower bound (≥4) and upper bound (≤8), then combine those checks with OP\_BOOLAND. Option B doesn't exist (OP\_WITHIN checks numeric range, not size), option C checks for exact equality (wrong), and option D measures stack depth instead of data size.
