Why each option
Kubernetes API versions typically follow a specific pattern, combining a version (e.g., `v1`, `v2`) with an optional stability indicator like `alpha` or `beta` and its release number.
`alpha1v1` and `beta3v3` are incorrect formats; the version number typically precedes the alpha/beta tag, as in `v1alpha1`.
`alpha1` and `beta3` are incomplete and incorrect formats for Kubernetes API versions; they lack the preceding 'v' and the primary version number (e.g., `v1`).
Kubernetes API versions commonly adhere to a format like `vX`, `vXbetaY`, or `vXalphaY`. `v1alpha1`, `v2beta3`, and `v2` are all valid examples representing different stages of API maturity and versioning.
`2.0` is not a standard Kubernetes API version format; API versions use 'v' followed by an integer, and potentially `alpha` or `beta` suffixes.
