Which option uses since correctly with the Present Perfect tense?

They have been friends since high school.

They have been friends since three years.

Since should be followed by a specific point in time, not a duration.

They were friends since high school.

This sentence is grammatically correct, but it uses the past simple (were friends), which suggests their friendship is no longer ongoing.

They will be friends since high school.

Since is not used with future tense. It shows when a past action started that is still relevant now.

Since is used with the Present Perfect tense to show when an action or event started in the past and continues to the present. For example:

I have worked here since 2019. - This means the action of working started in 2019 and is still true now.

Use since with a specific point in time (like a year, date, or a specific event).
