Final answer:
The given options for restoring the 'customer' table from a database named 'mydatabase' are not valid PostgreSQL commands.option a.
Step-by-step explanation:
The question revolves around restoring a specific table, named 'customer', from a PostgreSQL database called 'mydatabase'. To perform this restoration, you have to use pg_restore or psql command-line utility. However, the options provided seem to relate to the psql command, but they include incorrect flags. In standard PostgreSQL usage, there's no direct psql command that allows you to restore a single table using the format provided in the options. To restore a single table, you would typically need to first extract the table SQL using pg_dump and then load it using psql, like this:
pg_dump -t customer mydatabase > customer.sql
psql mydatabase < customer.sql
Among the provided options, none is a valid command for restoring a single table as they stand, but it is likely an incomplete snippet or a typo is present. To accurately answer the question, additional context or the correct options would be necessary.
