for fruit in "${fruits[@]}"; do echo $fruit; done

To iterate over all elements of an array, use for fruit in "${fruits[@]}"; do ... done. The [@] syntax expands to all elements.

Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.

✗
for fruit in "${fruits[*]}"; do echo $fruit; done
Why it's wrong here
${fruits[*]} expands to a single string with spaces.
✓
for fruit in "${fruits[@]}"; do echo $fruit; done
Why this is correct
Correct. Iterates over each element as separate items.
✗
for fruit in ${fruits[@]}; do echo $fruit; done
Why it's wrong here
Without quotes, elements with spaces would be split incorrectly.
✗
for fruit in ${fruits}; do echo $fruit; done
Why it's wrong here
${fruits} expands only the first element.
