Select the most more appropriate option to fill in the blank.

Sanidhya ______ to be promoted as he is very hard working.

deserves

The most appropriate option to fill in the blank is deserves.

The sentence "Sanidhya deserves to be promoted as he is very hard working" means that Sanidhya is worthy of being promoted because of his hard work. The word "deserves" is the most appropriate word to use in the blank because it accurately reflects the fact that Sanidhya has earned the promotion through his hard work.

The other options are not as appropriate.

• The word "doubts" means to have uncertainty or suspicion. This does not make sense in the context of the sentence, as Sanidhya is not uncertain or suspicious about whether he deserves to be promoted.
• The word "works" means to be employed or to do something for a living. This does not make sense in the context of the sentence, as Sanidhya is not simply working hard, he is working hard to the point that he deserves to be promoted.
• The word "tries" means to make an effort to do something. This does not make sense in the context of the sentence, as Sanidhya is not simply trying to be promoted, he has earned the promotion through his hard work.
