A. Dhruv said, "I am sick and tired of working for this company."
B. Dhruv said, "He was tired of that company."
C. Dhruv said to me, "I am sick and tired of working for this company."
D. Dhruv said, "I will be tired of working for that company."
Answer: Option A

As we are changing from indirect to direct speech 'he' changes to 'I' , 'was' changes to 'am' and 'that' changes to 'this'. Option A and C are similar but in the question 'to me' is not used hence option A is correct .
