Answer: Create JSON keys for the service account and execute `gcloud auth activate-service-account --key-file [KEY_FILE]`
The correct command to authenticate access to Google Cloud Platform with a service account using its JSON key file is `gcloud auth activate-service-account --key-file [KEY_FILE]`. This command imports the service account credentials from the specified key file and activates them for use in gcloud. The other options either use incorrect syntax (`authenticate` instead of `auth`) or specify an incorrect action (`service-account` instead of `activate-service-account`). For more details, refer to the [Google Cloud SDK documentation](https://cloud.google.com/sdk/gcloud/reference/auth/activate-service-account).
