Solutions
The correct answer is option 3 i.e. the more they spend.
Error concept: Improper use of the comparative correlative
What is wrong: The sentence is missing a second “the” which breaks the grammatical parallelism.
Grammatical concept: In comparative correlative constructions, both clauses should follow the structure:
"The more X, the more Y", "The less X, the less Y", etc.
Incorrectness of the concept in context: Saying "The more they earn, more they spend..." is ungrammatical because it omits the second "the."
How to correct: Add “the” before “more they spend.”
Correction: the more they spend
Final sentence: The more they earn, the more they spend on luxury.
Hence, the chosen option is the correct one.
