Identify the error in the sentence.
The room was more hot than comfortable.

Correct option is A

Option (a) contains an error.
Explanation: One-syllable adjectives typically form the comparative with -er, not more. Therefore, more hot is incorrect; it should be hotter. The idiomatic construction is “hotter than comfortable”, meaning the heat exceeded a comfortable level.
Grammatical rule used:
· Comparatives:
· One-syllable adjectives: -er (hot → hotter, tall → taller).
· Two+ syllables (and many irregulars): more/most (more careful, most beautiful).
· Avoid double comparatives (e.g., more better, more hotter).
· Example:
· Incorrect: The tea is more hot than warm.
· Correct: The tea is hotter than warm.
· Information booster: Some two-syllable adjectives can take either form depending on style (e.g., cleverer/more clever), but hot unequivocally takes -er/-est (hotter/hottest).
