Step-by-Step Solution

Solution:

Step 1: Check the length condition in select
The block selects words with length exactly 5.
Step 2: Identify words with length 5
Lengths: "apple"=5, "banana"=6, "cherry"=6, "date"=4. Only "apple" matches, so filtered=["apple"], puts filtered.join(", ") prints "apple".
Final Answer:
apple -> Option D
Quick Check:
Length == 5 only matches "apple" [OK]

Quick Trick: Count string length carefully when filtering [OK]
