Step-by-Step Solution
Solution:
Step 1: Understand symbol object identity
Symbols with the same name share the same object_id because they are unique and immutable.Step 2: Compare object_ids of sym1 and sym2
Both:applesymbols point to the same object, so their object_ids are equal, making the comparison true.Final Answer:
true -> Option CQuick Check:
Same symbol = same object_id [OK]
Quick Trick: Same symbol names share object_id, so comparison is true [OK]
Common Mistakes:
- Assuming different symbols have different object_ids
- Confusing symbols with strings which differ
- Expecting false because of separate variables
- Thinking symbols are mutable objects
