To answer this question, we need to understand the concept of a rule set in the context of applet personalization.
A rule set in applet personalization specifies the conditions under which a particular applet should be displayed or hidden. It consists of three main components: order condition, search specification, and set of actions.
Option A) Order condition - This option is incorrect because the order condition is a separate component of the rule set. It specifies the order in which applets should be displayed on a page.
Option B) Search Specification - This option is correct. The search specification is a part of the rule set and defines the conditions that need to be met for the applet to be displayed.
Option C) Set of Actions - This option is incorrect because the set of actions is another component of the rule set. It defines what actions should be performed when the conditions specified in the rule set are met.
Option D) Set of Events - This option is incorrect because the set of events is not a component of the rule set. Events are used to trigger the execution of applets but are not part of the rule set itself.
The correct answer is B) Search Specification. This option is correct because the search specification is a component of the rule set and defines the conditions that need to be met for the applet to be displayed.
