According to Oracle documentation2, your users can personalize the Springboards and Work Areas to

suit their individual working styles in these two ways: They can format certain tables by hiding and

showing columns, moving columns, and resizing columns, and they can use “+” under the Apps

section of the News Feed homepage. Springboards and Work Areas are user interface components

that enable users to access tasks and information relevant to their roles. Users can customize these

components by adding or removing tiles, changing layouts, filtering data, and formatting tables.

Therefore, options A and D are correct. Option B is incorrect because users have more control over

configuring their Springboards and Work Areas than just resizing columns. Option C is incorrect

because users do not need to have the System Administrator configuring pages for them using Page

Composer.
