Shib, In my previous post I neglected to respond to your choice, which stated The event, which has begun in 1960, has been going on for so many years. The present perfect (has + past participle) cannot refer to the start of a past event. Instead, the present perfect indicates the ongoing nature of an event. Thus, it is fine to say that The event has begun, indicating that the event began at some point in the past and continues to the present moment. However, it is a verb tense error to say that The event has begun in 1960.
Concerning the use of begun without have, has, or had, the only examples that come to mind are in modifying phrases such as the one in this problem.
The event, begun in 1960,...
Another example:
The company, begun in the early 20th century, continues to innovate and expand.
This could also be written with the modifier as an introductory phrase.
Begun in the early 20th century, the company continues to innovate and expand.
Hope that makes sense!
