• A. till
• B. since
• C. by
• D. for

Answer 1

Answer:

B. since

• Since is used with a specific point of time (year, date, day, etc.).

• 2015 is a specific year, so since is correct.

❌ for → used with a period of time (for 10 years)
❌ till / by → not suitable with present perfect continuous here
