Select the most appropriate option to fill in the blank.

Akbar had a ______ reign than Babar.

longer

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

The sentence is comparing the length of Akbar's reign to that of Babar. The word "longer" is the comparative form of the adjective "long." It is the most appropriate word to use because it accurately describes the fact that Akbar's reign was more extended in time than Babar's reign.

The other options are not as appropriate.

• More long is not a grammatically correct phrase. The correct phrase is "more lengthy."
• Longest is the superlative form of the adjective "long." It is not the correct form to use because the sentence is not comparing Akbar's reign to three or more reigns.
• Long is the positive form of the adjective "long." It is not the correct form to use because it does not accurately describe the fact that Akbar's reign was more extended in time than Babar's reign.
