Explanation:
The correct answer is option 'A' - "Abhishek, my teacher, is wearing a grey shirt."
Explanation:
Commas are used to separate elements in a sentence, and they are particularly important when it comes to introducing additional information or clarifying the structure of a sentence. In this case, we need to use commas to correctly identify the subject and provide additional information about it.
Here's a breakdown of each option and why they are correct or incorrect:
a) Abhishek, my teacher, is wearing a grey shirt.
- This is the correct answer. By placing a comma before and after "my teacher," we are providing extra information about the subject, Abhishek. The sentence flows smoothly and is grammatically correct.
b) Abhishek my teacher, is wearing a grey shirt.
- This option is incorrect. Without a comma after "Abhishek," the sentence lacks proper punctuation and clarity.
c) Abhishek, my teacher is wearing a grey shirt.
- This option is incorrect. Although a comma is placed after "Abhishek," there should also be a comma before "my teacher" to separate the additional information.
d) Abhishek my teacher is wearing, a grey shirt.
- This option is incorrect. The comma is incorrectly placed after "wearing," disrupting the flow of the sentence and creating confusion.
Conclusion:
To summarize, the correct answer is option 'A' - "Abhishek, my teacher, is wearing a grey shirt." By properly using commas to separate the additional information about the subject, the sentence becomes clear and grammatically correct.
