Select the most appropriate word to fill in the blank and make a meaningful sentence.

The Middle-East job market has always been a _______ destination for Indians.

lucrative

The most appropriate word to fill in the blank is lucrative.

The word "lucrative" means profitable or yielding a great deal of money. In this context, it makes sense to say that the Middle-East job market has always been a lucrative destination for Indians, as many Indians have found well-paying jobs in the Middle East.

The other options are not as appropriate. The word "luxury" means comfort or opulence. This does not make sense in the context of the sentence, as the Middle-East job market is not necessarily luxurious. The word "wealthy" means having a lot of money. This does not make sense in the context of the sentence, as not all Indians who work in the Middle East are wealthy. The word "costly" means expensive. This does not make sense in the context of the sentence, as not all jobs in the Middle East are costly.
