The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
After I retire, I started a second career / as a writer and published several books / which allowed me to share my stories / and insights with a wider audience.

Correct option is B

Option (b) contains an error.
Explanation: The verb "retire" is in the present tense, while the rest of the sentence uses past tense verbs ("started," "published"). To maintain tense consistency, "retire" should be changed to "retired."
Correct Sentence: After I retired, I started a second career as a writer and published several books.
Grammatical Rule: Tense consistency is essential within a sentence to maintain logical and chronological coherence.
Example:
· Incorrect: After I graduate, I worked as a teacher.
· Correct: After I graduated, I worked as a teacher.
