The correct answer is D. 35142.
The first option, 14523, is incorrect because it places “Rajasthan” before “India”. This is not correct, as Rajasthan is a state in India.
The second option, 35412, is incorrect because it places “is” before “Rajasthan”. This is not correct, as “Rajasthan” is a noun, and nouns cannot be verbs.
The third option, 35214, is incorrect because it places “in” before “Rajasthan”. This is not correct, as “in” is a preposition, and prepositions cannot be verbs.
The fourth option, 35142, is the correct answer because it places “Western” before “India”, “India” before “Rajasthan”, and “is” after “Rajasthan”. This is the correct order of the words, as “Western India” is a region in India, and “Rajasthan” is a state in India.
