Which conditions prevent users from submitting forms without entering values in related fields?

Selecting the option that pertains to preventing users from submitting forms without entering values in related fields is largely tied to the principle of form validation. The term "Require" means that certain fields must be filled out before the form can be submitted. This is a common feature in various data entry scenarios, ensuring that users provide essential information. By marking a field as required, the system checks for input before allowing form submission.

This mechanism is crucial for maintaining data integrity and ensuring that critical information is collected. If a field is marked as required and left blank, the system will typically generate a prompt or error message, guiding the user to complete the necessary fields prior to submission. In contrast, other terms such as "Enable," "Invalidate," and "Disable" do not directly control the ability to submit forms based on input. "Enable" generally refers to making fields editable, "Invalidate" might pertain to marking data as incorrect, and "Disable" would typically prevent interaction with the field altogether, but none enforce the completion of related fields before submission in the same way that "Require" does.
