Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
#!/bin/bash
Why it's wrong here
This is the shebang, which specifies the interpreter but does not affect error handling.
- ✗
trap ... ERR
Why it's wrong here
This can catch errors but does not automatically exit the script.
- ✓
set -e
Why this is correct
Correct. set -e exits on any command failure.
- ✗
set -x
Why it's wrong here
This enables debug tracing, not exit on error.
