To identify the sentence that has both commas in the right places, let's analyze each option:
Option A:
Hani, who is my elder sister, is 62 this year.
- This sentence correctly uses a pair of commas to set off the relative clause "who is my elder sister."
Option B:
Hani, who is, my elder sister is 62 this year.
- This sentence incorrectly places a comma after "is," which disrupts the sentence structure and does not provide any additional information.
Option C:
Hani who is, my elder sister, is 62 this year.
- This sentence incorrectly places a comma before "my elder sister," which separates the subject "Hani" from the verb "is" and disrupts the sentence structure.
Option D:
Hani who is my elder sister, is 62, this year.
- This sentence incorrectly places a comma after "62," which disrupts the sentence structure and does not provide any additional information.
Therefore, the correct answer is A:
Hani, who is my elder sister, is 62 this year.
This sentence correctly uses commas to set off the relative clause and maintains proper sentence structure.
