You have reinstalled the OS so now you should replace the keyboard. You need to get the keyboard from Apple. If you have removed the keyboard at any time, check to be sure the cable is properly seated.

Hi John,
            Will an external keyboard solve this issue?
Instead of replacing the keyboard in the mac book.

You can try a USB keyboard. Plug it in and then start up the computer.

Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

The screenshot you posted shows the option key being pressed. I would check that neither of the option keys are stuck down.You could try gently prying the key tops off and cleaning under the keys. If it isn't a physical sticking of the key, then it is an electrical defect and the keyboard need to be replaced.
If the option key regiseters as depressed, then an external keyboard will not work.  Did you spill something on your keyboard?
