Which sentence uses on correctly to show the topic being discussed?

The team is working on the new software update.

She fixed the bug by working on the weekend.

This use of on shows time, not the topic.

He logged in on his computer to check the server.

Here, on shows location, not the topic.

The meeting started on time with all developers present.

This on relates to time, not the subject discussed.

The preposition on can have many meanings, but in this task, it should be used to show the subject or topic being discussed or worked on.

Working on the new software update means the team is focusing their effort and attention on that specific project or topic.

Other sentences use on to show time (on the weekend, on time) or place/device (on his computer), which are different uses.
