Choose the correct alternative to replace the bold part to make the sentence grammatically correct.
They have published all detail of an invention.

Correct option is C

✔️ The correct substitution of the bold part is (c) all the details of the invention.
Explanation:
The word "detail" is a countable noun, and in this context, it should be used in its plural form “details.” Also, "the invention" is a specific noun, and hence requires the definite article “the”. The correct structure is: all the details of the invention.
Grammatical Rule Used:
· In English, when referring to specific items or concepts, the article “the” is used.
· Countable nouns (like “detail”) in general statements should be made plural when referring to multiple items.
· “All the details” implies a reference to every specific piece of information.
Explanation of the Rule in Hindi:
✔️ "Detail" एक गिनने योग्य संज्ञा है और जब हम सभी विवरणों की बात करते हैं तो इसे बहुवचन “details” में प्रयोग करते हैं।
✔️ "Invention" एक निश्चित वस्तु है, इसलिए इसके पहले “the” का प्रयोग करना आवश्यक है।
Meanings of Other Options:
· ❌ (a) All details of invention – Missing “the” before "invention" makes the phrase grammatically incomplete.
· Hindi: "Invention" से पहले “the” नहीं है, जिससे वाक्य त्रुटिपूर्ण हो जाता है।
· ❌ (b) All the details of invention – “The” is used with “details” but missing before “invention”.
· Hindi: "The invention" कहना चाहिए क्योंकि यह विशेष अविष्कार की बात कर रहा है।
· ❌ (d) No improvement – Incorrect because singular “detail” is wrong in this context.
· Hindi: “Detail” एकवचन है जबकि बहुवचन “details” होना चाहिए।
