Answer: B

Why this is correct
By default, there are wildcard table rules () for the create, read, write, and delete operations and wildcard field rules (.) for the personalize_choices, create, and save_as_template operations. When you create a table, create ACL rules for it unless you want to use the provided wildcard rules.

Why the other options are wrong
"Table rules () and field rules (.) both cover the same four operations: create, read, write, and delete" … The field rules cover personalize_choices, create, and save_as_template, not the same four operations as the table rules.
"Field rules (.) are provided for read and write, and no other operations are covered at the field level" … The wildcard field rules are for personalize_choices, create, and save_as_template. Read and write are among the wildcard table rules.
"Wildcard rules are provided for tables (), while the base system provides no field-level wildcard rules (.)" … The base system provides wildcard field rules (.) as well, for personalize_choices, create, and save_as_template.

Why every user passes a table ACL
Because the STAR () table rules match every table, every user must pass at least one table ACL rule. The glide.sm.default_mode property sets whether those wildcard table rules allow or deny read, write, create, and delete when they are the only match.
