Select a specific value from the dropdown list and automatically diverted to another tab

Dear all,

I have a sample file here (attached). What I want to achieve is:

If "TEK 3" is selected from the dropdown box in tab "Model_A", then it will automatically divert user to tab "Model_B". Otherwise, nothing will happen and the user continues to stay on tab "Model_A".

I hope the macro is able to monitor if "TEK 3" is selected at any time to act accordingly.

Many thanks for help
