Correct option is B
The correct option to fill in the blank is
(b) career.
· The sentence suggests that Kiran had a short duration of being a writer, which is referred to as a "career."
· "Caress" means a gentle touch or stroke, and it doesn't fit the context.
· "Carer" refers to someone who provides care to others, and it doesn't make sense in this sentence.
· "Carrier" typically means a person or thing that carries something, and it's not the right word for describing Kiran's role as a writer.
So, option (b) "career" is the appropriate word to complete the sentence.
