Select the most appropriate synonym of the given word.
SOLID

Correct option is B

The correct synonym for the word "SOLID" is "firm."
· Firm describes something that has a solid, stable structure that is not easily compressed.
· This aligns well with the definition of solid, which implies a state of matter characterized by structural rigidity and resistance to changes in shape or volume.
· Example: The mattress was firm, offering good support for the back.
· Other options:
· (a) "flat" relates to a smooth and even surface without any significant rise or depression, not directly synonymous with solidity.
· (c) "vacant" and (d) "hollow" both imply emptiness, which contradicts the filled nature of something solid.
