Read the following sentence carefully and check each part for error. Mark the option that indicates the error.
The accident happened due to the engine driver’s less attention to the signals.

Correct option is C

The error lies in option (c).

• Explanation: The phrase “less attention” is incorrect here. The proper expression is “little attention” because attention is an uncountable noun. With uncountable nouns, little is used, not less, when we talk about insufficient quantity in such sentence structure.
• Correct sentence: The accident happened due to the engine driver’s little attention to the signals.
• Grammatical rule (English): Less is generally used for comparative degree, whereas little is used with uncountable nouns to indicate small quantity.
• व्याकरण नियम (Hindi): अगणनीय संज्ञाओं के साथ कम मात्रा बताने के लिए little का प्रयोग किया जाता है। Less का प्रयोग प्रायः तुलनात्मक रूप में होता है।

So the correct answer is (c)
