Question

My friend ...... here since 1985. a. works b. working c. has been working d. is working

Answer 1

My friend (c) has been working here since 1985. - Present Perfect Continuous

Answer 2

The correct answer is c. has been working.

"My friend has been working here since 1985."

This sentence indicates an ongoing action that started in the past (1985) and continues to the present. The present perfect continuous tense ("has been working") is used to express this continuous action over a period of time.
