What is the difference between a natural join and an inner join with an explicit ON clause?
Correct! Well done.
Incorrect.
The correct answer is D) A natural join automatically matches columns with the same name in both tables, which can produce unexpected results if unrelated columns happen to share a name; an explicit ON clause makes the join condition clear and predictable

NATURAL JOIN implicitly joins on all identically named columns, which is convenient but fragile — adding a new column with a matching name in either table silently changes the join semantics. Explicit ON clauses are preferred because they document intent and avoid such surprises.
