The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
I, you and she/ have been working happily/ in the same company and in the same branch/ for the last nine years.

Correct option is C

Option (c) contains an error.
Explanation: The correct order of pronouns in a sentence depends on the context. In affirmative/declarative sentences, the standard and polite order is:
2nd person (you), 3rd person (he/she/they), and 1st person (I) → i.e., “ You, she and I.”
The incorrect order "I, you and she" is grammatically and conventionally inappropriate in this case.
Grammatical rule used:
· In declarative sentences, pronouns are ordered as: 2nd + 3rd + 1st person.
· In negative or apologetic contexts, the order is usually: 1st + 2nd + 3rd person (e.g., “I, you and he were responsible.”)
Example:
Correct: You, she and I have completed the project successfully.
Incorrect: I, you and she have completed the project successfully.
